Patent number: 5051390Abstract: A process for the preparation of a cogel catalyst comprises preparing an aqueous solution containing a soluble compound of an alkali or alkaline earth metal, a soluble metal compound which is thermally decomposable to a metal oxide capable of converting methane to higher hydrocarbons and a hydrolysable silane under such conditions that a homogenous cogel is formed. The cogel catalyst is effective for oxidizing methane to higher hydrocarbons and exhibits greater selectivity and lasts longer than conventional prior art catalysts. A process for using the cogel catalyst to effect oxidation of methane is also described.Type: GrantFiled: October 10, 1989Date of Patent: September 24, 1991Assignee: The British Petroleum Company, p.l.c.Inventors: Paul A.
