Poisoning with catalytic converter regenerative manner, and the suffering

摘要

PROBLEM TO BE SOLVED: To provide a catalyst heating and regenerating method which causes neither a thermal damage such as sintering of catalyst components nor activity deterioration of the catalyst and provide an apparatus for the method.;SOLUTION: The catalyst regeneration method is a method for regenerating a catalyst, which is poisoned by an poisonous substance in a waste gas and deteriorated in the activity, by blowing hot air to the catalyst, and is characterized in that the temperature is controlled so as to keep the temperature distribution in a packed part of the catalyst within a range of proper regeneration temperature ±30°C.;COPYRIGHT: (C)2002,JPO
