【Abstract】 Fischer-Tropsch synthesis has been studies over spray-dried precipitated iron catalyst in a spinning basket gradientless reactor.The result shows that reaction temperature has more obvious influence on the formation of C 1-C 2 paraffin than of C 3-C 4 paraffin,and has a larger effect on the formation of C 3-C 4 olefin than that of C 3-C 4 paraffin.The increase of H 2/CO feed ratio first accelerates the formation of C 3-C 4 paraffiin and C 2-C 4 olefiin,then restrains it.The increase of reactioin pressure improves the formation of C 1-C 4 paraffin and C 2-C 4 olefin.The hydrocarbon distribution of FT products indicates a typical double-α distribution and break is at C 6(α 1=0.55,α 2=0.89).更多还原
