PROMOTED CARBIDE-BASED FISCHER-TROPSCH CATALYST, METHOD FOR ITS PREPARATION AND USES THEREOF

摘要

A precursor for a Fischer-Tropsch catalyst includes a catalyst support, cobalt or iron on the catalyst support and one or more noble metals on the catalyst support, wherein the cobalt or iron is at least partially in the form of its carbide in the as-prepared catalyst precursor, a method for preparing said precursor and the use of said precursor in a Fischer-Tropsch process.

主权项

1. A precursor for a Fischer-Tropsch catalyst comprising:
(i) a catalyst support; (ii) a cobalt-containing precursor on the catalyst support, the cobalt-containing precursor being selected from cobalt benzoylacetonate, cobalt carbonate, cobalt cyanide, cobalt hydroxide, cobalt oxalate, cobalt oxide, cobalt nitrate, cobalt acetate, cobalt acetylacetonate, cobalt carbonyl or a mixture of two or more thereof; and (iii) one or more noble metals on the catalyst support, wherein the catalyst support comprises silica and the surface of the silica is coated with a non-silicon oxide refractory solid oxide.
