Due to the increase in pollutant gases emission which are released in the atmosphere through the combustion of petroleum byproducts, much concern has risen about air quality and global warming caused by such gases, highlighting the need to find a substitute for fossil fuels. Biofuels produced from oilseeds are a functional example, which present some advantages such as not releasing sulphur during combustion, taking part in the carbon closed cycle and boosting agribusiness. Thus, the objective of this study was to analyze the physico-chemical properties of the rapeseed oil and biodiesel, produced from 3 (three) hybrids submitted to different levels of stress caused by environmental factors throughout the plant development. The sowing was established in the city of Tibagi – PR with the rapeseed hybrids 43, 61 and 571, sowed on 4 dates from April to May 2013 in 4 replications, totaling 46 plots. The data collected was submitted to variance analysis, employing the software SISVAR and the differences regarding averages were compared through the Tukey test (p≤0,05). Different sowing dates affected grain yield (kg ha-1), seed oil content (g kg-1) and oil per hectare yield (kg ha-1). The crop presented stable development at temperatures 10 and 20 °C, while temperatures below zero °C influenced the production negatively. The unsaturated fatty acid average obtained was 915 g kg-1, regarding hybrids and sowing dates, indicating good potential of this seed as raw material for biodiesel production.
Com o aumento da emissão de gases poluentes lançados na atmosfera pela combustão de derivados do petróleo, surgiram preocupações com a qualidade do ar e aquecimento global causados por estes gases, ressaltando a necessidade de encontrar um substituto para combustíveis fósseis. Os biocombustíveis produzidos a partir de oleaginosas são exemplos funcionais, que além de não emitirem enxofre na combustão, também fazem parte do clico fechado do carbono e movimentam o agronegócio. Assim sendo, o objetivo deste trabalho foi analisar as propriedades físico-químicas do óleo e biodiesel de canola, produzidos a partir de 3 (três) híbridos submetidos a diferentes níveis de stress durante o desenvolvimento da planta, causado por fatores ambientais. A semeadura ocorreu na cidade de Tibagi – PR com híbridos de canola Hyola 43, 61 e 571, semeados em 4 datas de abril a maio de 2013 com 4 repetições, totalizando 46 parcelas. Os dados coletados foram submetidos à análise de variância, pelo software SISVAR e as diferenças entre médias foram comparadas pelo teste de Tukey (p≤0,05). As diferentes datas de semeadura afetaram o rendimento de grãos (kg ha-1), o teor de óleo nas sementes (g kg-1) e o rendimento de óleo por hectare (kg ha-1). A cultura teve um desenvolvimento estável nas temperaturas entre 10 e 20 °C, sendo que temperaturas abaixo de zero °C exercem influência negativa na produção. A média dos ácidos graxos insaturados obtidos foi de 915 g kg-1, para híbridos e datas de semeadura indicando um bom potencial dessa cultura como matéria prima na produção de biodiesel.

Повний текст джерелаThe search for sustainable sources of liquid fuels, in order to replace oil with a renewable source and reduce emissions of greenhouse gases, provided prominence to the biodiesel. This biofuel is a renewable source of clean energy and produced from different raw materials. Brazil has a promising potential as a producer of these raw materials as well as the biodiesel itself, because it has favorable public policies and has the necessary technology. In Brazil, the production and use of biodiesel is based on recent institutional framework in order to develop and introduce this fuel in the Brazilian energy matrix. The diversification of raw materials to produce biodiesel is among the main objectives of the programs established by the government. However, in Brazil, this biofuel is predominantly produced using soybeans. In order to understand the reasons for the predominance of this oilseed, we evaluated the competitiveness, economic efficiency and political effects in biodiesel production by productive chains of soybean, canola and sunflower in Rio Grande do Sul. For this, we used the method of the Policy Analysis Matrix (PAM), which assists in analyzing and defining public policies and identifying possible market failures that might impact on economic outcomes of agribusiness chains, just as assesses the competitiveness and efficiency of these systems. The results indicated the superiority of biodiesel production from soybean chain, as this presents greater competitiveness and economic efficiency. On the other hand, policy distortions were observed which disadvantage the private and social profitability of the three chains studied, such as the farmer’s payment system based on the seed weight, even if the percentage and oil prices differ substantially from the raw materials, besides the significant differences in technological standards adopted in crops.

Повний текст джерелаThe high cost of traditional feedstock and their limited availability for biodiesel production, prevent the expansion of production and consumption of biofuels in several parts of the world, including Brazil. In Paraná there is the possibility of producing oilseed crop with short cycle period between harvests of summer and winter crops in places where they anticipate the sowing of corn, and thus complementing the traditional feedstock for biodiesel production. In order to evaluate the agronomic performance and growth of crambe and juncea canola in different sowing dates, focusing on the implementation of this culture among the intervals of summer and winter seasons, the FMS Brilhante cultivars and Terola 25A85 were evaluated in three sowing dates (05/15, 06/01 e 06/15/14), with two phytosanitary treatments (with the application of the fungicide trifloxystrobin + prothioconazole and without fungicide). The parameters analysed for these two oilseeds were plant height, thousand seed weight, grain yield, oil content and oil yield. The sowing dates had had influence only on plant height for crambe and, for juncea canola a significant effect on plant height, grain yield and oil yield. The best sowing date for juncea canola was the first sowing date (15/05). The fungicide application gave higher grain yield for crambe and for juncea canola, higher thousand seed weight, grain yield and oil yield. Both cultures did not produce satisfactorily, not being viable as a third crop in Londrina in the year of 2014 due to climatic conditions, plus the incidence of bacterial disease in crambe. Regarding the evaluation of growth, as the seedlings are delayed, the lower the duration of the cycle and biomass production.

Повний текст джерелаIn this work the polymerization of epoxidized fatty acids, derived from soybean and canola biodiesel, were performed, in the presence of cis-1,2-cyclohexanedicarboxylic anhydride and triethylamine. The synthesis of magnetic nanoparticles of Fe3O4 and CoFe2O4 are presented, which were obtained from the co-precipitation method. The aim of this study was to coat the synthesized nanoparticles with polymers obtained from epoxidized fatty acids in oreder to reduce the magnetic nanoparticles agglomeration. The nanoparticles coating was evidenced by solubility tests and infrared spectroscopy analysis, in which, the stretching band of Fe-O, at 570-565 cm-1, was observed. Transmission electron microscopy showed the increase in nanoparticles diameter, from 12.2 nm (Fe3O4), to 13.2, 13.6, and 14.6 nm, after their coating with PAO-Fe, PAGS-Fe, and PAGCa-Fe, respectively. The particle size calculated from X-ray diffractograms were 11.4, 10.8, 9.9 and 11.1 nm, for nanoparticles of Fe3O4, PAO-Fe, PAGS-Fe, and PAGCa-Fe, respectively. Whereas, the particles size of CoFe2O4, PAO-Co, PAGS-Co, and PAGCa-Co nanoparticles, were 10.8, 9.8, 10.1 and 10.4 nm, respectively. Magnetic properties were characterized using the Vibranting Sample Magnetometer and a superparamagnetic behavior in iron nanoparticles (Fe3O4) and ferromagnetic in cobalt nanoparticles (CoFe2O4) were observed. The results presented here demonstrated that the methodology can open a new field of investigation, once there is no reports on the coating of iron or cobalt nanoparticles with polymers obtained from the fatty acids of biodiesels.

Повний текст джерелаThe biodiesel production generates large volumes of residues, which when improperly disposed have potential for environmental contamination. The objectives of this study were to evaluate the adding sawdust filtration untreated with a Oxisol and with an Paleudalf, producing an organic compound from the mixture of sawdust filtration with manure aiming to know the immediate potential and residual fertilizer of this organic compound in canola cultivated in these two soil types. Soil samples were placed in respirometric flasks and added 2; 4 and 8 t ha-1 sawdust filtration with and without addition of N, P and K recommended for the culture of canola. During 120 days we quantified C-CO2 production, the dynamics of these nutrients and the concentration of heavy metals. In pots in a greenhouse, the organic compound produced was mixed with these soils at planting or six months before. The doses were 0, 0.6, 1.2, 2.4 and 4.8 t ha-1, with or without supplemental N, and we quantified the availability of nutrients in the soil, the accumulation of dry mass and nutrients in tissues of canola. The biodegradation of sawdust filtration in the soil was high but limited by K in Oxisol and by P in Paleudalf. The addition of this residue in both soils cause reduced availability of N, K in the Oxisol, but did not increase the levels of heavy metals. The organic compound produced presents characteristics that allow its use in agriculture and its addition to soils at the time of sowing or six months before increases the availability of N, P and K, and replaces total or partially the mineral fertilization of canola.
A produção do biodiesel gera grandes volumes de resíduos, que quando dispostos de maneira inadequada, possuem potencial de contaminação ambiental. Os objetivos deste trabalho foram avaliar a disposição da serragem de filtração sem tratamento prévio em um Latossolo e em um Argissolo e produzir um composto orgânico, a partir da mistura da serragem de filtração com esterco bovino, visando conhecer o potencial fertilizante imediato e residual deste composto na canola, cultivada nestes dois tipos de solo. Amostras dos solos foram acondicionadas em frascos respirométricos e adicionadas de 2; 4 e 8 t ha-1 de serragem de filtração, com e sem adição de N, P e K recomendados para a cultura da canola. Durante 120 dias, foi quantificada a produção de C-CO2, a dinâmica destes nutrientes e a concentração de metais pesados. Em vasos em casa de vegetação, o composto orgânico produzido foi misturado a estes solos, no momento da semeadura ou seis meses antes. As doses avaliadas foram 0; 0,6; 1,2; 2,4; e 4,8 t ha-1, com ou sem complementação de N, e quantificou-se a disponibilidade de nutrientes no solo, o acúmulo de massa seca e nutrientes nos tecidos da canola. A biodegradação da serragem de filtração foi moderada no solo, porém limitada pelo K no Latossolo e pelo P no Argissolo. A adição deste resíduo nos dois solos causa redução da disponibilidade de N e de K no Latossolo, mas não elevou os teores de metais pesados. O composto orgânico produzido apresenta características que permitem seu uso agrícola. A sua adição aos solos, no momento da semeadura ou seis meses antes, aumenta a disponibilidade de N, P e K, e substitui total ou parcialmente a adubação mineral da canola.

O crescimento econômico ocorrido a partir do final do século XX teve como fonte motora o desenvolvimento tecnológico sustentado pelo consumo de energias não renováveis, ou seja, derivadas basicamente do petróleo, do carvão e do gás natural. Esse modelo chegou a um ponto de inflexão em função do aumento crescente dos preços do petróleo e as previsões de esgotamento dessa fonte de energia. Neste contexto, os países estão buscando, através de políticas públicas, promover novas fontes de energias renováveis para manter o crescimento de forma sustentável. E a utilização de biodiesel como combustível vem despontando com um potencial promissor em todo o mundo, sendo um mercado que cresce rapidamente, em virtude principalmente dos aspectos ambientais envolvidos.

The economic growth which occurred from the end of the twentieth century had as a source driving the technological development sustained by the consumption of non-renewable energy, which is mainly derived from oil, coal and natural gas. This model has reached a point of inflection in the light of increasing oil prices and forecasts of depletion of energy source. On this context, countries are seeking by public politics to promote new sources of renewable energy, to maintain growth in a sustainable way. And the use of biodiesel fuel is coming with a potential promising in the world, with a market that is growing quickly, mainly because of the environmental involved aspects. This research concerns the choice of materials for the biodiesel production, especially coming from canola, sunflower, castor bean and soybean, in which this last one is configured as the main raw material. In addition, inside the limits of Rio Grande do Sul state, the agricultural zoning enabled the canola development, sunflower and cast

Повний текст джерелаThe use of synthetic antioxidants at biofuel factories with the objective of extending the useful life of these fuels is common. However, it was bearing in mind the intent of using the greatest number of renewable resources in the production of biodiesel that the idea of studying the addition of plant products in biodiesel came up. This is because they are rich in phenolic compounds, which are responsible for the antioxidant activity. The study consisted of two stages. The first stage was to study, using thermogravimetry (TGA), the influence of rosemary leaves and yerba mate immersed in canola and sunflower biodiesel (both produced in labs) for a period of 90 days without any pro-oxidant factors. The second stage encompassed the extraction of plant extracts from orange peels, rosemary leaves, and yerba mate by Soxhlet extraction with the use of organic dichloromethane solvents. The extracts obtained at this point were added in different proportions (1,000 mg/L and 2,000 mg/L) in canola and sunflower biodiesel and exposed to two different conditions. The first condition was exposing the modified biodiesel to atmospheric air, light and room temperature during 60 days; the second condition consisted of exposing the biodiesel to heat during the same period in a greenhouse at 60 ºC. The influence of these additions and biodiesel exposures were tracked using TGA and acidity index analyses. At the end, it was clear that adding rosemary leaves and yerba mate directly into biodiesels and isolating them from pro-oxidant factors resulted in no significant contributions coming from these products since both the unmodified biodiesels and the modified biodiesels showed similar Ti values (initial degradation temperature). For this reason, it was necessary to start another work phase, where all biodiesels were exposed to pro-oxidant factors, making possible the analysis of the efficiency of the additions. No plant extract exceeded the antioxidant action of the BHT (butylated hydroxytoluene), however they all showed antioxidant activity during the 60-day period since pure B100 showed higher acidity index levels and lower Ti levels compared to the modified samples. The biodiesels exposed to the first condition showed similar results in the pure B100 and the modified B100, unlike what happened with the samples exposed to heat. When the biodiesels were exposed to heat, the activity of the additives became clearer. It was possible to conclude that among the biodiesels with added plant extracts, the canola B100 added with 2,000 mg/L of orange peel extract and sunflower B100 added with 2,000 mg/L of yerba mate extract showed higher thermal-oxidative stability.

Повний текст джерелаEight Texel x Polwarth crossbred wethers (31.1±3.8 kg BW), four with duodenal cannulae were used in a replicated 4x4 Latin square design to evaluate effects of canola meal (44.4% CP, 29.5% NDF and 3.2% EE; DM basis) on intake, whole-tract digestibility, microbial protein synthesis and nitrogen retention. The basal diet consisted of ad libitum access to sudangrass (10% refusals). Treatments were sudangrass only (control), or supplemented with 5, 10, or 15 g/kg BW of concentrate, offered twice daily at 0800 and 1700h. Concentrate was 90% canola meal and 10% finely ground corn. Wethers were adapted to diets for 10 d followed by a 5-d collection period. Forage DMI decreased linearly (P<0.001) as supplement intake increased, and was 26.1% lower in supplemented animals in relation to the control group. Total DMI, which included forage and supplement, increased 30.6% and digestible OM intake increased 41% with supplementation. Supplementation did not affect DM and OM digestibility, while depressed NDF digestibility and improves N digestibility. Microbial protein synthesis and microbial efficiency were not affected by supplementation. Nitrogen retention was markedly higher in supplemented animals (236% higher), and was due mainly to the higher duodenal flow of amino acids. Supplementation with canola meal improves total nutrient supply, however, exerted a negative effect on forage intake and fiber digestibility in wethers.
Este estudo foi conduzido com o objetivo de avaliar a inclusão de farelo de canola na dieta de ovinos e seus efeitos sobre o consumo de volumoso, digestibilidade, síntese protéica microbiana ruminal e retenção de nitrogênio. Oito ovinos machos cruzados Texel x Polwarth (31,1±3,8 kg PV), quatro destes implantados com cânula duodenal foram utilizados em um delineamento quadrado Latino 4x4 duplo com períodos de 15 dias, sendo 10 dias adaptação e cindo dias coleta de dados. A dieta experimental basal foi composta de capim Sudão (ad libitum, 10% de sobras) e os tratamentos foram: capim Sudão (controle), ou suplementado com 5, 10 ou 15 g/kg PV de concentrado, ofertados duas vezes ao dia às 08:00 e 17:00h. O concentrado foi 90% farelo de canola e 10% de milho moído. O consumo de MS da forragem decresceu linearmente (P<0,001) com o aumento no consumo de suplemento e foi em média 26,1% menor em relação ao grupo controle. O consumo total de MS que inclui forragem e suplemento aumentou 30,6% e o consumo de MOD aumentou 41% nos animais suplementados. Não houve efeito da suplementação sobre a digestibilidade da MS e da MO, todavia, houve redução na digestibilidade da FDN e aumento na digestibilidade do N. A síntese e a eficiência de síntese protéica microbiana ruminal não foram afetadas (P>0,05) pela adição do suplemento à dieta. A retenção de N foi substancialmente maior(P<0,001) nos animais recebendo o farelo de canola (236%), e foi devida principalmente à maior oferta de aminoácidos. A suplementação aumentou a oferta total de nutrientes e a retenção de nitrogênio em ovinos, todavia, exerceu um efeito negativo sobre o consumo de forragem e a digestibilidade da fibra.

Este estudo tem como objetivo determinar o custo unitário, em litro por hectare, de produção de biodiesel no Rio Grande do Sul a partir das culturas de soja, de girassol e de canola, partindo do custo de produção agrícola até o custo por litro de biodiesel destas culturas. Para o custo de produção agrícola realizou-se uma comparação entre as estruturas de custos de diversas instituições, comparando suas quantidades para a determinação da proposta de estrutura de custos, e foi realizada a posterior precificação no mercado, com base nas quantidades definidas. O cálculo do custo por litro de biodiesel iniciou com o cálculo de extração do óleo vegetal através de dois processos, extração por solvente e por prensagem, encontrando uma distinção de valores em relação aos processos. Já para os custos de produção do biodiesel, foram considerados os custos calculados nesta pesquisa e além destes, os custos com insumos, mão-de-obra, depreciação e energia elétrica que foram calculados e cedidos pela AFUBRA para a realização deste estudo. Os resultados apontam para os valores de R$ 1,73 para o biodiesel de girassol e de R$ 1,59 para o biodiesel de soja pelo método de extração por solventes; e de R$ 1,64 para biodiesel de girassol e de R$ 1,72 para biodiesel de soja pelo método de extração por prensagem. Observa-se que em alguns momentos o biodiesel de girassol é mais vantajoso em relação ao biodiesel de soja e, em outros, o biodiesel de soja tem esta vantagem.
The objective of this study is determining the unitary cost, in liters per hectare, of biodiesel production in the Brazilian state of Rio Grande do Sul, from soy, sunflower and canola cultures, since the cost of the agricultural production to the per liter cost of biodiesel of these cultures. To obtain the agricultural production costs we performed a comparison between the cost structures of several organizations, comparing their quantities to determine the cost structure proposal; and we performed the subsequent pricing in the market based on defined quantities. The estimation of biodiesel per liter costs started by calculating the vegetal oil extraction through two processes, extraction by solvent and extraction by pressing, finding the difference in values of both processes. For biodiesel production costs we considered those costs estimated in this research and also the expenses with raw materials, labor, depreciation and electric energy, which where estimated and granted by AFUBRA for the development of this study. The results show values of R$ 1.73 for sunflower biodiesel and R$ 1.59 for soy biodiesel by the solvent extraction method; and R$ 1.64 for sunflower biodiesel and R$ 1.72 for soy biodiesel by the extraction by pressing method. It is possible to observe that in some moments sunflower biodiesel is more advantageous in relation to soy biodiesel and, in others, soy biodiesel is more advantageous.
