Zusammenfassung:	Methods of using a catalyst preburner upstream of a catalyst burner, such as an anode tailgas oxidizer (ATO), in fuel processing applications. The me thods prepare a hydrogen containing gas mixture which can be effectively com busted in a single ATO. The catalyst preburner will convert raw fuels into a gas mixture including hydrogen. This hydrogen containing gas mixture then m ixes with the required air flow and anode tailgas and off-gas from a pressur e swing adsorption unit before being introduced into the catalyst burner. Th e methods address the start-ups needs of an ATO as well as the requirement t hat an ATO be able to burn both liquid and gas fuels in a single unit.
