Fischer-Tropsch synthesis using iron based catalyst in a microchannel reactor: Performance evaluation and kinetic modeling

Kinetics of Fischer–Tropsch Synthesis in a 3-D Printed Stainless Steel Microreactor Using Different Mesoporous Silica Supported Co-Ru Catalysts

“…They claimed that a mechanism based on the adsorption and desorption have a satisfactory fit to the experimental data with the activation energies for the formation of methane, paraffin and olefin to be around 70 kJ/mol, 113 kJ/mol, and 91 kJ/mol, respectively [89]. In order to improve the efficiency of FT synthesis significantly, detailed kinetic rate expressions were derived which is very similar to our work reported in literature for both fixed bed reactor as well as microreactor using iron or cobalt-based catalyst [80,81,90,91]. The elementary steps in the above studies were used to develop kinetic mechanisms considering FT reactions with and without water gas shift (WHS) reactions occurring on the surface of the catalysts forming intermediates with active sites.…”

“…In the microchannels of the microreactor, the flow of reactants is basically laminar. The complexity of the microchannel microreactor increases due to the parabolic type velocity profile; so, an average velocity profile is approximated during the development of the model for the microreactor system [80]. The outlet concentrations of the limiting reactant (CO), which was related to the rate of reaction, were calculated by an in-line GCMS.…”

“…In order to determine the most suitable kinetic model for a particular catalyst, all possible combinations of FT reactions were considered and rate equations were developed based on CO conversion. A number of Langmuir-Hinshelwood and Eley-Rideal models have been developed for kinetics of CO hydrogenation to hydrocarbons in different types of reactors over the past few years [80][81][82]. In this study, it was assumed that the FT reactions occur only at active sites and proposed six possible mechanisms for FT reactions to develop kinetic models in the microchannel microreactor as shown in Table 2.…”

Optimization of biohydrogen production using acid pretreated corn stover hydrolysate followed by nickel nanoparticle addition

“…These mature techniques are facing great challenge, as more stringent environmental and emission regulations are being enforced. The current proposed imminent mitigation strategy lies in simultaneous carbon capture and storage or carbon capture and utilization, which converts the captured CO 2 into hydrocarbons on industrial scale such as via Fischer‐Tropsch synthesis technology . The great barriers, that is, cost‐effectiveness, reliabilities, therefore, needed to be overcome before hydrogen energy can be maturely implemented to replace current existing infrastructures of the fossil based energy production and utilization.…”

“…The current proposed imminent mitigation strategy lies in simultaneous carbon capture and storage or carbon capture and utilization, which converts the captured CO 2 into hydrocarbons on industrial scale such as via Fischer-Tropsch synthesis technology. [4][5][6] The great barriers, that is, cost-effectiveness, reliabilities, therefore, needed to be overcome before hydrogen energy can be maturely implemented to replace current existing infrastructures of the fossil based energy production and utilization. Due to the appealing advantages such as locate availability, cost-effectiveness in decentralized energy productions, reduction of greenhouse gas emissions, and local new job creations, the energy generation from biomass has attracted great interests during the last two decades.…”
