- Аннотация: Reduction of CO2 with hydrogen into CO was studied for the first time on aluminasupported Co and Fe catalysts under supercritical conditions with the goal to produce either CO orCH4 as the target products. The extremely high selectivity towards methanation close to 100% wasfound for the Co/Al2O3 catalyst, whereas the Fe/Al2O3 system demonstrates a predominance ofhydrogenation to CO with noticeable formation of ethane (up to 15%). The space–time yield canbe increased by an order of magnitude by using the supercritical conditions as compared to thegas-phase reactions. Differences in the crystallographic phase features of Fe-containing catalystscause the reverse water gas shift reaction to form carbon monoxide, whereas the reduced iron phasesinitiate the Fischer–Tropsch reaction to produce a mixture of hydrocarbons. Direct methanationoccurs selectively on Co catalysts. No methanol formation was observed on the studied Fe- andCo-containing catalysts
