Cobalt-based fischer-tropsch catalyst, cobalt-based catalyst precursor, and processes for preparing a catalyst precursor and a catalyst

摘要

"COBALT-BASED FISCHER-TROPSCH CATALYST, COBALT-BASED CATALYST PRECURSOR, AND PROCESSES FOR PREPARING A CATALYST PRECURSOR AND A CATALYST". The present invention relates to a cobalt-based Fischer-Tropsch catalyst which includes a porous catalyst support and metallic cobalt crystallites within the support. The catalyst has a proportion of its cobalt in a reducible form, this ratio being expressible in 87 mass%, based on the total mass of the catalyst prior to reduction. The catalyst also has, when just reduced, a size distribution of the monomodal Gaussian metallic cobalt crystallites, a surface area of metallic cobalt, in m ^ 2 ^ per gram of catalyst, of 0.14 87. at 1.03? and a catalyst geometry that ensures a stabilized Fischer-Tropsch synthesis efficiency factor of 0.9 or greater.
