Fe-Cu-K2O-La2O3catalysts were prepared by special impregnation on the SiO2, ZrO2and 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-ZrO2play 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 H2to CO2is 3 . The conversion of CO2is more than 64%. Light olefin’s selectivity is more than 25%.

In order to increase the activity and selectivity towards to light olefins in the Fischer-Tropsch synthesis, new support for the role of iron (Fe) are presented. Thus, SBA-15 was synthetized and doped with different alkaline metals preserving the structural characteristics of the mesoporous solid. The samples were characterized by X-ray diffraction at low angles, N2 adsorption, atomic absorption spectroscopy, CO2 desorption at programmed temperature and isopropanol test. The alkaline metals (Li, K and Cs) introduction into the channels of the solid, generate basic sites of different strength that are not present in the SBA-15 without doping and do not produce significant changes in the structural and textural properties of the SBA-15, only a densification in the walls of the channels is evidenced. According to the alkaline metal used and through CO2 adsorption and isopropanol decomposition, it was possible to established the order by the total number of sites: Li >> K » Cs, and the force order for both types of sites (weak and intermediate): Li > Cs > K.
