Fe-Cu-K2O-La2O3 catalysts were prepared by special impregnation on the SiO2, ZrO2 and SiO2-ZrO2. Some factors of influence on catalytic activity were researched,such as the content of active component Cu and La, calcination temperature, reaction temperature and space velocity. The structures and physicochemical properties of the catalysts were characterized by XRD and TEM. When the SiO2-ZrO2 play the role of carrier , Fe:Cu:K:La = 100:15:7:7:250:250, the calcination temperature is 773K, the reaction temperature is 613K and space velocity is 2400ml • h-1 • g-1 (cat), the catalyst shows the best catalytic activity , if the reaction pressure is 0.1 Mpa , and the molar ratio of H2 to CO2 is 3 . The conversion of CO2 is more than 64%. Light olefin’s selectivity is more than 25%.
