Abstract (en)
[origin: WO2007143960A1] The invention relates to a method for regenerating a reformer to which, in continuous reformer operation, a mixture of fuel (12, 14) and oxidant (16, 18, 20) is fed, with an average air ratio ?<SUB>1</SUB>, wherein the air ratio is changed for the purpose of regeneration of the reformer. According to the invention, it is provided that the regeneration takes place in a phase where the reformer is switched off, and that the reformer is operated over several consecutive time intervals, with an increased air ratio ?<SUB>2</SUB>>?<SUB>1</SUB> compared to the reformer operation. According to the invention, it can also be provided that the regeneration takes place in a start phase of the reformer, and that the reformer is continuously operated with an increased air ratio ?<SUB>2</SUB>>?<SUB>1</SUB> compared to the reformer operation, until a critical temperature threshold has been reached. The invention also relates to a system with a reformer and a control for carrying out a method according to the invention.
