Abstract
A solid composition of matter is disclosed consisting essentially of sodium, potassium, a Group IA metal or a Group IA metal and a Group IIA metal, titanium, oxygen and, optionally, at least one of a halogen and tin, in which at least one of the sodium, the potassium, the Group IA metal or the Group IIA metal is present in an amount in excess of any amount present in electrically neutral compounds of the metal, the titanium and oxygen. The above compositions are particularly useful as solid contact materials for the oxidative conversion of feed organic compounds to product organic compounds, particularly in the presence of a free oxygen containing gas. A method for such conversion is also disclosed. In a preferred embodiment a method for the oxidative conversion of methane, such as natural gas, to higher hydrocarbons, particularly ethylene and ethane, is disclosed in which the methane and a free oxygen containing gas are contacted with a Group IA metal, a Group IIA metal, or a Group IA metal and a Group IIA metal, titanium, oxygen and, optionally, a halogen and/or tin.
