摘要

CO2 hydrogenation reaction was performed on precipitated iron catalysts which were promoted by Si, Zn, K and Cu. The optimum SiO2 content in the catalysts is about 15 wt% relative to Fe2O3 mass. With reaction temperature raised, CO2 conversion is increased continually, but CO and CH4 selectivity only fluctuate in a narrow range which is beneficial to the synthesis of C2+ hydrocarbons. Two kinds of catalyst filling constitution were experimentally compared in order to increase the yield of C5+ hydrocarbons.
