Der volle Inhalt der QuelleThe national sugarcane industry, coming from the energy policy autonomy of the 70s, seeks increase its portfolio productive improvement of productive and energy efficiency. Hydrogen and dissolved metabolites production by biological process is a relatively recent research line, however it, may represent an alternative for this sector, maximizing energy production and increasing the value-added compounds production. Based on these principles, the aim of this study was to evaluate the hydrogen and dissolved metabolites production by means of the dark fermentation from compounds of the sugarcane industry; sucrose (RS), sugarcane juice (RC), molasses (RM) and vinasse (RV) with 5,000 mg COD L- 1in thermophilic anaerobic fluidized bed reactor (55°C) submitted to hydraulic retention time (HRT) of 8, 6, 4, 2, and 1h. The inoculum was obtained from methanogenic upflow anaerobic sludge blanket reactor employed to digestion of sugarcane stillage in thermophilic temperature range (55°C). The highest hydrogen production rates (HPR) of these reactors were obtained when operating in HRT 1h, which were 194.9, 501.4, 303.4, and 40.7 mL H2 h-1 L-1 to RS, RC , RM, and RV respectively. The best hydrogen yield (HY) were duped in differents HRT; 1.97, 3.01, 0.65, and 2.5 mol H2 mol-1 sacarose when RS, RC , RM, and RV were operated in 4, 6, 2, and 1h , respectively. When were produced the biggest HPR, the predominant dissolved metabolites were lactic acid, acetic acid, butyric acid, propionic acid, malic acid and ethanol, dependent on the substrate used in each reactor. Therefore, evidence of the possibility of hydrogen, organic acids and ethanol production by dark fermentation applied to substrates that industry, confirming that the production of energy and high value-added products may be an alternative application for their compounds.

Der volle Inhalt der QuelleThe use of renewable fuels has been highlighted in recent years, mainly due to the environmental impacts generated by the use of fossil fuels and their scarcity. Among the renewable fuels highlights the biodiesel, whose production process displays as the main byproduct crude glycerol, which has instigated in recent years, intense debates about a problem of its destination and final disposal. Although it is used in the chemical industry, its impurities content limits its industrial processing. In order to add value to this crude residue and to contribute to the production of bioenergy, this work aimed to evaluate the production of biofuels hydrogen and methane, as well as chemical intermediates from crude glycerol as substrate in anaerobic fluidized bed reactors (AFBR), mesophilic (30°C), using mixed culture inoculum. The AFBR-H2, with the objective of producing hydrogen and soluble metabolites, was submitted to a concentration of 10 g.L-1 of glycerol and a variation of the hydraulic retention time (HRT) of 8, 6, 4, 2, 1 and 0.5 h. The AFBR-CH4, with the intention of producing methane, operated under fixed HRT of 24 h, subjected to the variation of the glycerol concentration of 1, 2, 3, 4, 5 and 7 g.L-1 and, therefore, of the organic loading rate (OLR) of 1, 2, 3, 4, 5 and 7 kgCOD.m-3d-1, respectively. In the AFBR-H2, the maximum values of hydrogen content in the biogas (69.2%), hydrogen volumetric productivity (1.90 L.h-1.L-1) and hydrogen yield (0.28 molH2.mol-1glycerolconsumed) were verified in the HRT of 0.5 h. The 1,3-propanediol was highlighted among the metabolites produced, with a maximum yield of 0.57 mol1,3-PDO.mol-1glycerolconsumed, reached in the TDH of 8 h. In the AFBR-CH4, the higher methane content in the biogas (83.0%) was detected in the OLR of 1 kgCOD.m-3.d-1, a higher volumetric productivity of methane (2.26 L.d-1.L-1) in the OLR of 5 kgCOD.m-3.d-1 and the maximum yield (0.19 m3CH4.kg-1CODapplied or 0.77 molCH4.mol-1glycerolconsumed) in the OLR of 4 kgCOD.m-3d-1. Therefore, the results evidenced the possibility of producing biofuels and value-added metabolites using crude glycerol as a substrate at the anaerobic digestion process.

This study aimed to optimize the production of hydrogen and other metabolites using crude glycerol as substrate, through design of experiments (DoE) and statistical process optimization. The first study aimed at optimizing the operational parameters of the fermentation process, and therefore, a mesophilic AFBR reactor was operated on 10 different phases, distributed as a combination of HRT and the glycerol concentration (Gc) proposed by a matrix containing CCD array containing 10 experimental trials. The HRT varied to 9.24h to 0.76h, while Gc ranged from 17.1g / L to 2.9 g / L. The results showed that the maximum conversion of glycerol (CG), 98.4%, was obtained using substrate concentrations lower than 5.0 g/L. The maximum yield (0.17 mol H2 / mol consumed glycerol) and H2 content in the produced biogas (87.4%) were achieved at concentrations greater than 10.0 g/L and HRT of 5h. Among the main soluble metabolites produced, 1,3-propanediol (1,3-PD) and propionic acid (HPr) stood out. The maximum yield of 1,3-PD (1.05 mol 1,3-PD / mol consumed glycerol) was obtained with 10.0 g/L glycerol in HRT of 9,24h, whereas the maximum yield of HPr (0.71 mol HPr / mol consumed glycerol) was achieved with 15.0 g/L of glycerol and HRT of 2h. The second study, in turn, consisted of optimizing the culture medium components (glycerol, KH2PO4, yeast extract and vitamin B12), through batch tests, and subsequent application in AFBR reactor. The maximum hydrogen and ethanol yields, 0.006 and 0.291 mol / mol consumed glycerol, was obtained in optimal culture medium consisting of 26.53 g/L glycerol, 1.75 g/L KH2PO4, 0.0076 g/L B12 and 0.5 g/L yeast extract. The application of optimal culture medium in a continuous reactor did not result in improvement of H2 and ethanol yields, however, caused an increase in 1,3-PD yield, reaching a maximum of 0.38 mol 1.3-PD / mol consumed glycerol.
O presente trabalho teve como objetivo otimizar a produção de hidrogênio e outros metabólitos, utilizando glicerol bruto como substrato, empregando técnicas de planejamento experimental e otimização estatística de processos. O primeiro estudo visou a otimização de parâmetros operacionais do processo fermentativo, e para tanto, um reator RALF mesofílico foi operado em 10 fases distintas, distribuídas conforme uma combinação do TDH e da concentração de glicerol (Cg) proposta por uma matriz de um DCCR contendo 10 condições experimentais. O TDH variou de 9,24h a 0,76h, enquanto a Cg variou de 17,1 g/L a 2,9 g/L. Os resultados obtidos mostraram que a máxima conversão de glicerol (CG), 98,4%, foi obtida utilizando concentrações de substrato menores que 5,0 g/L. O máximo rendimento (0,17 mol H2/mol glicerol consumido) e conteúdo de H2 no biogás produzido (87,4%) foram atingidos em concentrações superiores a 10,0 g/L e TDH de 5h. Dentre os principais metabólitos solúveis produzidos, 1,3-propanodiol (1,3-PD) e ácido propiônico (HPr) se destacaram. O máximo rendimento de 1,3-PD (1,05 mol 1,3-PD/mol glicerol consumido) foi obtido com 10,0 g/L de glicerol em TDH de 9,24h, enquanto que o máximo rendimento de HPr (0,71 mol HPr/mol glicerol consumido) foi alcançado com 15,0 g/L de glicerol e TDH de 2h. O segundo estudo, por sua vez, consistiu na otimização de componentes do meio de cultura (glicerol, KH2PO4, extrato de levedura e vitamina B12), através de ensaios em batelada, e posterior aplicação em RALF. Os máximos rendimentos de H2 e etanol, 0,006 e 0,291 mol/mol glicerol consumido, foram obtidos em meio de cultura ótimo constituído por 26,53 g/L de glicerol, 1,75 de KH2PO4, 0,0076 g/L de B12 e 0,5 g/L de extrato de levedura. A aplicação do meio de cultura otimizado em reator contínuo não resultou na melhoria dos rendimentos de H2 e etanol, no entanto, ocasionou um aumento no rendimento de 1,3-PD, alcançando 0,38 mol 1,3-PD/mol glicerol consumido.

In the present study, an anaerobic fluidized bioreactor combined with an anaerobic fluidized membrane bioreactor (AFBR-AFMBR) was used to for treat municipal wastewater at ambient temperature. The objectives of this study were to evaluate the start-up time and the performance using zeolite as carriers and the performance of the AFBR-AFMBR. During the start-up period, the reactor system was operated in semi-continuous mode and at a hydraulic retention time (HRT) of 1 d and an organic loading rate (OLR) of 1 g/m3/d with influent chemical oxygen demand (COD) of 1000 mg COD/L (made by synthetic wastewater). The reactor system reached to steady state with a pH level of 7, COD removal efficiency higher than 90% and 1 L/d of the steady biogas production. The microorganisms were successfully attached onto the carrier. Thereafter, the reactor system was changed to continuous mode operation at 3.5 h of total HRT for treating municipal wastewater (73 to 220 mg COD/L) at ambient temperature ranged from 20 to 35oC. The reactor performance reached to 70 to 90% of COD removal, 96% of total suspended solids (TSS) removal and 0.13 L CH4/g CODremoved of specific methane production. The membrane module in AFMBR can be continuously used for 333 d at a flux of 10 LMH without chemical cleaning. Besides, the reactor system only needed 0.015 kWh/m3 of pumping energy requirement and can generate 0.0024 kWh/m3 of methane energy. The above results revealed that the AFBR-AFMBR is a high efficiency energy-saving system for treating municipal wastewater.
