Abstract

A method of preparing catalyst compositions of cobalt composited with ternary metal oxide supports of substituted titania having the general formula Co/Ti_1-x M_x O₂ where x ranges from 0.01 to 0.14 and M is selected from the group consisting of silicon, zirconium, and tantalum and wherein the titania is an anatase polymorph stable under oxidative regeneration temperatures from about 400° to about 750° C.

Claims

1. In a Fischer-Tropsch process, under Fischer-Tropsch reaction conditions, including contacting with a feedstream comprising a CO and H₂ reaction mixture, a 400°

-750°

C. regeneration stable catalyst composition comprising cobalt on a substituted ternary metal oxide of titania having the general formula Co/Ti_1-x M_x O₂ wherein x is from 0.01 to 0.14 and M is selected from the group consisting of silicon, zirconium, and tantalum, wherein the titania is an anatase polymorph.
