High surface area ceramic catalysts and the manufacture thereof

Abstract

A process for making a ceramic catalyst material includes mixing a catalyst precursor material with a mineral particulate to form a mixture; adding a binder, silicon carbide, and a parting agent to the mixture to form unfired spheroids; and heating the unfired spheroids at a temperature effective to oxidize the silicon carbide and the catalyst precursor material to form the ceramic catalyst material. In another embodiment, the process includes the addition of a catalyst metal oxide salt to an aluminosilicate hydrogel aggregate mixture. Once the mixture sets, the set mixture is heated to a temperature to effective to produce a high surface area ceramic catalyst material.
