Abstract
Disclosed are methods for regenerating an at least partially deactivated methane oxidation catalyst comprising contacting the catalyst with a gas stream comprising carbon monoxide (CO) under conditions that are net lean of stoichiometry and at a temperature of about 125° C. to about 450° C. over a period of time. Also provided are methane oxidation catalysts that have been regenerated according to the disclosed methods, as well as methods of catalyzing methane oxidation.

A method for regenerating an at least partially deactivated methane oxidation catalyst comprising contacting the catalyst with a gas stream comprising carbon monoxide (CO) under conditions that are net lean of stoichiometry and at a temperature of about 125° C. to about 450° C. over a period of time.
A method of catalyzing methane oxidation comprising:
- exposing a methane oxidation catalyst to a source of methane until the catalyst is at least partially deactivated;
- and,
- contacting the at least partially deactivated catalyst with a gas stream comprising carbon monoxide (CO) under conditions that are net lean of stoichiometry and at a temperature of about 125° C. to about 450° C. over a period of time until the catalyst is at least partially regenerated.
