| 20080249197 | Process for the Production of Methanol from Methane using a Supported Transition Metal Catalyst - A process for the selective oxidation of methane to methanol using a supported transition metal catalyst has been developed. Examples of the transition metals which can be used are copper and palladium, while an example of a support is silica. Optionally, the catalyst can contain a modifier component such as cesium. Generally the process involves contacting a gas stream, comprising methane, a solvent such as trifluoroacetic acid and an oxidizing agent such as air or hydrogen peroxide with the catalyst, at oxidation conditions to produce a methyl ester, e.g. methyl trifluoroacetate. Finally, the methyl ester is hydrolyzed to yield a methanol product stream. | 10-09-2008 |
