05/02429 Development of bimodal cobalt catalysts for Fischer-Tropsch synthesis

Abstract

A catalyst support with spatially-connected small pores and large pores, as a distinct bimodal pore structure, has been developed, which has excellent advantages in solid-catalysis reactions because the large pores provide pathways for rapid molecular transportation and the small pores serve a large area of active surface. The ZrO 2 -SiO 2 bimodal catalyst presented the best reaction performance in slurry-phase FTS, because the spatially promotional effect of bimodal structure and the chemically promotional effect of the porous zirconia were available at the same time inside the large pores of original silica gel.
