英文摘要A series of core-shell catalysts with different shell thickness were synthesized and the effect of microporous silica shell on product distribution of Fischer-Tropsch synthesis was analyzed. Fe3O4 core was prepared by hydrothermal method and the amorphous SiO2 shell was coated on the Fe3O4 core by sol-gel method. N-2 adsorption-desorption analysis indicated an irregular and microporous silica shell and the pore size distribution moved to smaller diameter with the shell thickness increased. In Fischer-Tropsch synthesis, inactive silica shell increased catalytic activity (FTY) and stability by restricting catalyst cracking and sintering. Product distribution shifted to C-1-C-4 gaseous hydrocarbons with the increasing shell thickness probably due to the diffusion limitations on reactants/products and structure confinement and separation effect of microporous silica shell on restricting the growth of catalytic active particles. Selectivities of C5+ were restricted within 10% for core-shell catalysts. WGS reaction activity is reduced as well, which constrains side reaction and amplifies FTS catalytic productivity to hydrocarbons.
