Abstract

Applicants have developed a novel catalyst composition comprising a crystalline metal oxide having the empirical formula: AvBt+wNixD(Gu−)yOz, where A is an alkali metal (e.g. Na), B is a basic metal (e.g. Ca), D is a framework component (e.g. P), and G is an anionic species (e.g. OH−). Nickel may be present in the framework of the crystalline metal oxide, dispersed thereon, or both. Preferably, the metal oxide component has an apatite or hydroxyapatite crystal structure. These crystalline metal oxide components have been found to have improved performance in partial oxidation and light hydrocarbon (e.g. methane) reforming to produce synthesis gas. A new process for synthesizing these metal oxides is also disclosed.
