Metal oxide supported iron-nickel nano-alloys in the reverse water-gas shift reaction
… is first activated to carbon monoxide via the reverse water- gas shift (RWGS) reaction. The RWGS is thermodynamically limited. CO and CO2 methanation are favoured over the RWGS at industrially preferred reaction conditions and there is a need for low temperature catalysts with a high CO …

Kinetics and Reaction Engineering Aspects of Syngas Production by the Heterogeneously Catalysed Reverse Water Gas Shift Reaction
… of a process for CO2 utilisation and/or syngas production, the catalytic hydrogenation of CO2 using commercial Ni/Al12O19 and Al2O3 catalysts was studied. The experiments were performed in a down-flow fixed bed quartz reactor at atmospheric pressure. The reverse water gas shift (RWGS) …

Carbon Dioxide Gas Separation from Syngas to Increase Conversion of Reverse Water Gas Shift Reaction via Polymeric and Mixed Matrix Membranes
… efficient separation strategy for effluent gases in the Reverse Water Gas Shift (RWGS) reaction to increase the overall conversion of CO2 to CO. This process involves a separation and recycling process to reuse the unreacted CO2 from the RWGS reactor. The carbon monoxide produced from this …

Catalytic Reforming of Biogas for Syngas Production
Biogas is a mixture of methane and carbon dioxide produced from the anaerobic microbial digestion of biomass. It is an inexpensive, local source of energy but is usually wasted because the CO₂ content dilutes the quality of the fuel. Dry and auto-thermal reforming are catalytic methods that convert …

Kinetic study of dry reforming of Methane with Ni over different supports and Pt/Al2O3
… investigate CH4 and CO2 influence of on the DRM reaction, the different partial pressure of CH4 and CO2 were dosed into the reactors in a parameter field test. In order to study the influence of products CO and H2 on reaction network, respective co-feeds CO and H2 were added. Therefore, the …

Carbon Supported Metal Carbide Catalysts for the Reduction of Carbon Dioxide
… preventing their exposure to air or passivation gases. The petcoke-based carbon prepared had higher surface areas and pore volumes (~2000 m2/g and > 1 cm3/g) than other commercial carbons (1000-700 m2/g and ~0.5 cm3/g) which enhanced the catalytic performance towards CO2 reduction. …

Application of Molybdenum Carbide Catalysts for the CO2-assisted Oxidative Dehydrogenation of Ethane
… these severe process conditions, competing side reactions and catalyst deactivation via coking are the major challenges. Co-feeding an oxidant significantly decreases the reaction temperature. The oxidative dehydrogenation of ethane to ethylene, using CO2 as the oxidant (CO2-ODH), has earned a …

Dry reforming of associated natural gas using catalytic membrane reactors.
The mitigation and utilization of greenhouse gases, such as carbon dioxide (CO2), are among the most important challenges in the area of energy research. Dry reforming of propane (C3H8) (DRP), which uses both CO2 and C3H8 as reactants, is a potential method to utilize the previously-mentioned gases …

Novel empowered supports for iron-based Fischer-Tropsch in a power-to-liquids process
… the past, FT synthesis has been used to produce gasoline and diesel from coal and natural gas. However, with increasing demand for renewable and sustainable energy sources, there has been renewed interest in using FT to produce clean fuels 2 . The FT synthesis process takes place in the presence …

TIMELESS QUESTIONS AND MODERN CHALLENGES: A JOURNEY FROM THE ORIGIN OF LIFE IN HYDROTHERMAL VENTS TO ELECTROCHEMICAL CO2 REDUCTION
… potentials of the involved redox couples shift as a function of pH; consequently, a reaction that would be non-spontaneous if both half-reactions occurred at the same pH, can become spontaneous (ΔG < 0) when the two processes take place under distinct pH conditions. First, two model …
