Abstract
A variable gas generator is disclosed which is capable of producing a wide variety of product gas compositions heretofore produced only by either exothermic gas generators or endothermic gas generators or a combination of gas generators. The variable gas generator includes a nitrogen membrane module producing a nitrogen-oxygen feed gas which is combined with a hydrocarbon fuel and fed into a conventional endothermic gas generator. By controlling the nitrogen membrane module to produce a desired oxygen-nitrogen feed gas and by controlling the addition of methane and the catalyst bed temperature of the gas within the endothermic generator, a wide variety of product gas composition with carbon potential varying anywhere from one to 80% combustibles can be produced.
