Abstract

See full text

A gas generator and process for converting a fuel into an oxygen-depleted gas and/or hydrogen-enriched gas. The gas generator is preferably used for generating protection gas or reducing gas for start up, shut down or emergency shut down of a SOFC or SOEC. The process for converting fuel into oxygen-depleted gas and/or a hydrogen-enriched gas includes combusting the fuel in a primary catalytic burner with an oxygen-containing gas to produce a flue gas with oxygen, combusting or partially oxidizing the flue gas comprising oxygen with excess fuel in a secondary catalytic burner to produce a gas with hydrogen and carbon monoxide, and reducing the trace amounts of oxygen from the gas comprising traces of oxygen and obtaining an oxygen-depleted gas, or reducing the carbon monoxide present in the gas by conversion to carbon dioxide or methane to obtain a hydrogen-enriched gas.
