Abstract
A method of preparing catalyst compositions of cobalt composited with ternary metal oxide supports of substituted titania having the general formula Co/Ti.sub.1-x M.sub.x O.sub.2 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.degree. to about 750.degree. C.
Claims1
In a Fischer-Tropsch process, under Fischer-Tropsch reaction conditions, including contacting with a feedstream comprising a CO and H.sub.2 reaction mixture, a 400.degree.-750.degree. C. regeneration stable catalyst composition comprising cobalt on a substituted ternary metal oxide of titania having the general formula Co/Ti.sub.1-x M.sub.x O.sub.2 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.
