ABSTRACT:
The combustible component of a gas stream of low heating value is combusted using less than a stoichiometric amount of oxygen with minor production of carbon monoxide due to the use of an oxygenation catalyst comprising at least three metals in a perovskite-type crystal structure. This combusted gas can be directly vented to the atmosphere after energy has been extracted from it for a useful purpose.
