Resumen

The search for new stable and active catalysts of Fischer-Tropsch synthesis is one of the key directions for production of liquid fuels from alternative raw materials. Stabilization of the active phase is the main task in the development of catalysts for hydrogenation of CO into liquid fuels. This problem can be solved by choosing the optimal support, as well as the synthesis method. This work is devoted to the development of new polymer mono– and bimetallic Ru-containing catalysts for liquid phase Fischer-Tropsch synthesis. It is shown that the use of 1% Ru-HPS and 10% Co — 1% Ru-HPS allows to obtain a high yield of gasoline hydrocarbons (more than 70%), providing a high conversion of CO (up to 23%). The selected polymer-based systems showed high stability in the Fischer-Tropsch synthesis process.

Resumen

This paper presents the effect of a synthesis method for cobalt catalyst supported on hydrotalcite material for Fischer-Tropsch synthesis. The hydrotalcite supported cobalt (HT-Co) catalysts were synthesized by co-precipitation and hydrothermal method. The prepared catalysts were characterized by using various techniques like BET (Brunauer–Emmett–Teller), SEM (Scanning Electron Microscopy), TGA (Thermal Gravimetric Analysis), XRD (X-ray diffraction spectroscopy), and FTIR (Fourier Transform Infrared Spectroscopy). Fixed bed micro reactor was used to test the catalytic activity of prepared catalysts. The catalytic testing results demonstrated the performance of hydrotalcite based cobalt catalyst in Fischer-Tropsch synthesis with high selectivity for liquid products. The effect of synthesis method on the activity and selectivity of catalyst was also discussed. Copyright © 2017 BCREC Group.

Resumen

Steam methane reforming has been a conventional process to produce synthesis gas which is an important feedstock to many chemicals. However, for gas to liquid (GTL) applications this reforming process is not suitable as it produces synthesis gas with very high hydrogen to carbon monoxide ratio than required by the Fischer Tropsch synthesis in GTL line. In this work, a GTL process is designed in which synthesis gas is produced by steam reforming from a natural gas feedstock containing relatively substantial carbon dioxide contents in it. Synthesis gas composition is tailored by tail gas recycling from the Fischer Tropsch products. Process simulation and optimization is performed on Aspen HYSYS to produce synthesis gas with hydrogen to carbon monoxide ratio of 2 which is desired in GTL technology.

Resumen

The Fischer-Tropsch process was studied in a laminar flow slurry bubble column reactor. Prior to the experiments, hydrodynamic studies were done in a cold-flow model of the reactor. A mathematical model was also developed for the reactor, based on the kinetic data of an iron-based catalyst. The present modeling approach employed enabled the computation of the extent of gas contraction due to reaction. Six sets of experimental runs were carried out to validate the model, the last utilizing biosyngas, produced by the gasification of willow. The model developed was suitable to predict the performance of the reactor, with the rate parameters adjusted, necessitated by the fact that the catalyst activity changes with time-on-stream. The effect of a number of selected parameters on the Fischer-Tropsch process was also investigated.

Resumen

The present work analyses the techno-economic potential of Power-to-Liquid routes to synthesize Fischer-Tropsch paraffin waxes for the chemical sector. The Fischer-Tropsch production unit is supplied with hydrogen produced by electrolysis and CO2 from biogas upgrading. In the analysis, 17 preferential locations were identified in Germany and Italy, where a flow of 1 t/h of carbon dioxide was ensured. For each location, the available flow of CO2 and the capacity factors for both wind and solar PV were estimated. A metaheuristic-based approach was used to identify the cost-optimal process design of the proposed system. Accordingly, the sizes of the hydrogen storage, electrolyzer, PV field, and wind park were evaluated. The analysis studied the possibility of having different percentage of electricity coming from the electric grid, going from full-grid to full-RES configurations. Results show that the lowest cost of Fischer-Tropsch wax production is 6.00 €/kg at full-grid operation and 25.1 €/kg for the full-RES solution. Wind availability has a key role in lowering the wax cost.

Resumen

Diesel fuel is largely consumed by transportation services, and diesel fuel from direct coal liquefaction and Fischer–Tropsch fuel have been produced as alternatives in coal-rich areas. However, the physicochemical characteristics of the two fuels are not quite the same as those of diesel fuel derived from crude oil. Therefore, the spray development, the combustion characteristics and the emissions of diesel fuel from direct coal liquefaction, Fischer–Tropsch fuel and commercial diesel fuel were studied in this paper. The spray development was investigated by using planar laser-induced fluorescence, and the results showed that the spray characteristics of coal-liquefied fuel were similar to those of commercial diesel fuel. Diesel fuel from direct coal liquefaction has a longer ignition delay and a higher heat release rate from premixed combustion than commercial diesel fuel does because of its lower cetane number at low loads. However, the same combustion characteristics with commercial diesel fuel can be achieved by mixing diesel fuel from direct coal liquefaction and Fischer–Tropsch fuel in a ratio of 3 to 1. With increasing engine load, the in-cylinder temperature and the pressure increased which reduced the effect of the cetane number on the ignition delay and the combustion process. The regulated emissions from Fischer–Tropsch fuel were the lowest of these fuels; the unregulated emissions measured by Fourier transform infrared spectroscopy, however, were slightly higher than those of the other two fuels.

Resumen

In situ characterization of catalysts gives direct insight into the working state of the material. Here, the design and performance characteristics of a universal in situ synchrotron-compatible X-ray diffraction cell capable of operation at high temperature and high pressure, 1373 K, and 35 bar, respectively, are reported. Its performance is demonstrated by characterizing a cobalt-based catalyst used in a prototypical high-pressure catalytic reaction, the Fischer–Tropsch synthesis, using X-ray diffraction. Cobalt nanoparticles supported on silica were studied in situ during Fischer–Tropsch catalysis using syngas, H2 and CO, at 723 K and 20 bar. Post reaction, the Co nanoparticles were carburized at elevated pressure, demonstrating an increased rate of carburization compared with atmospheric studies.

Resumen

Catalytic hydrogenation of CO2 has great potential to significantly reduce CO2 and contribute to green economy by converting CO2 into a variety of useful products. The goal of this study is to assess and compare the techno-economic and environmental measures of CO2 catalytic conversion to methanol and Fischer–Tropsch-based fuels. More specifically, two separate process models were developed using a process modeler: direct catalytic conversion of CO2 to Fischer–Tropsch-based liquid fuel/high-calorie SNG and direct catalytic conversion of CO2 to methanol. The unit production cost for each process was analyzed and compared to conventional liquid fuel and methanol production processes. CO2 emissions for each process were assessed in terms of global warming potential. The cost and environmental analyses results of each process were used to compare and contrast both routes in terms of economic feasibility and environmental friendliness. The results of both the processes indicated that the total CO2 emissions were significantly reduced compared with their respective conventional processes.

Resumen

As a clean renewable energy, biomass energy is now gradually being used in electric power, chemicals, heating and other related industries with great potential, and further research is also ongoing in depth. At the same time, because the demand of the construction of environment-friendly society, feed gas from biomass gasification for Fischer-Tropsch fuel synthesis in this way also has gained more and more attention. For the selection of ideal way to obtain synthetic fuels with relatively high system efficiency from biomass, this paper simulation for a variety of processes and different gasification conditions based on Gibbs free energy minimization method. The impacts of pre-treatment of biomass, temperature of gasification and pressure are analyzed. In the evaluation of energy efficiency of the system, an exergy analysis of biomass integrated process is presented. All parts of the process were calculated and compared, which mainly includes the gasification, pre-treatment, HRSG, compression, purification, WGS and FT reactor sections. The results showed that in the process the largest exergy losses take place in the gasifier section, and the pre-treatment of biomass materials for this part will have a greater impact on exergy loss.

Resumen

In the process of CO hydrogenation to olefins by the Fischer–Tropsch synthesis, the support is a key factor in the activity, selectivity, and thermal and chemical stability of the catalysts, and magnesium aluminate spinel has recently been reported to be very effective.

Resumen

The interest in Gas-to-Liquid technology (GTL) is growing worldwide because it involves a two-step indirect conversion of natural gas to higher hydrocarbons ranging from Liquefied Petroleum Gas (LPG) to paraffin wax. GTL makes it possible to obtain clean diesel, naphtha, lubes, olefins, and other industrially important organics from natural gas. This article is a brief review discussing the state-of-the-art of GTL, including the basics of syngas manufacturing as a source for Fischer-Tropsch synthesis (FTS), hydrocarbons synthesis (Fischer-Tropsch process), and product upgrading. Each one is analyzed, and the main characteristics of traditional and catalysts technologies are presented. For syngas generation, steam methane reforming, partial oxidation, two-step reforming, and autothermal reforming of methane are discussed. For Fischer–Tropsch, we highlight the role of catalysis and selectivity to high molecular weight hydrocarbons. Also, new reactors technologies, such as microreactors, are presented. The GTL technology still faces several challenges; the biggest is obtaining the right H2:CO ratio when using a low steam-to-carbon ratio. Despite the great understanding of the carbon formation mechanism, little has been made in developing newer catalysts. Since 60–70% of a GTL plant cost is for syngas production, it needs more attention, particularly for developing the catalytic partial oxidation process (CPO), given that modern CPO processes using a ceramic membrane reactor reduce the plant’s capital cost. Improving the membrane’s mechanical, thermal, and chemical stability can commercialize the process. Catalytic challenges accompanying the FTS need attention to enhance the selectivity to produce high-octane gasoline, lower the production cost, develop new reactor systems, and enhance the selectivity to produce high molecular weight hydrocarbons. Catalytically, more attention should be given to the generation of a convenient catalyst layer and the coating process for a given configuration.

Resumen

Bimetallic cobalt-containing catalysts supported on alumina have been studied in the Fischer-Tropsch synthesis. It has been shown that a promotion of Co/Al2O3 by iridium leads to dispergation of both metals. It was supposed that the metal dispergation occurred due to M-M interaction with formation of the bimetallic nano-particles of cluster type. These particles have the high catalytic activity, selectivity and stability in the Fischer-Tropsch synthesis. It was observed that by regulation of the process conditions it is possible to obtain the definite hydrocarbon fractions. Thus, the increase both CO+H2 ratio and space velocity is accompanied by high olefin yield.

Resumen

Синтез Фишера-Тропша все больше привлекает внимание ученых, так как позволяет получать широкий спектр продуктов, на выход и молекулярно-массовое распределение которых оказывает влияние как катализатор, так и условия проведения процесса. В данной работе было изучено влияние на скорость и выход целевых продуктов - жидких углеводородов таких параметров процесса, как температура, состав синтез-газа, нагрузка на катализатор. На основании полученных зависимостей были найдены основные макрокинетические параметры - энергия активации и порядок реакции синтеза Фишера-Тропша. The Fischer-Tropsch synthesis is increasingly attracting the attention of scientists, since it allows a wide range of products to be obtained. The yield and molecular mass distribution of the products strongly depend on both the catalyst and the process conditions. In this work, the influence of such parameters as temperature, synthesis gas composition, the catalyst loading on the process rate and yield of the target products was studied. Based on the obtained dependencies, the main macrokinetic parameters were found -the activation energy and the reaction order of the Fischer-Tropsch synthesis.
