Abstract
A method of oxidizing that portion of a methanol fuel which has not been burned in an internal combustion engine is disclosed. Briefly, the method includes the following steps. A methanol fuel is burned in an internal combustion engine thereby to produce exhaust gases which contain unburned methanol. The exhaust gases containing the unburned methanol are passed over a catalyst consisting essentially of silver dispersed on a washcoat material. The washcoat material is in turn dispersed on a substrate. In this manner, the unburned methanol is oxidized to carbon dioxide and water without any significant production of aldehydes, ethers or carbon monoxide.

A method of oxidizing that portion of a methanol fuel which has not been burned in an internal combustion engine, which method comprises the steps of:
- burning a methanol fuel in an internal combustion engine thereby to produce exhaust gases which contain unburned methanol;
- and
- passing said exhaust gases containing said unburned methanol over a catalyst consisting essentially of silver dispersed on a washcoat material, which washcoat material is dispersed on a substrate, whereby said unburned methanol is oxidized to carbon dioxide and water without production of significant amounts of aldehydes, ethers or carbon monoxide.
