Abstract
A method for regenerating a catalyst containing molybdenum as an active component comprising subjecting a catalyst, which has been deactivated through the use for a reaction, with or without a molybdenum source added thereto, to a heat treatment in a reducing gas atmosphere under specific temperature conditions and then subjecting same to a further heat treatment in a gaseous atmosphere containing molecular oxygen and at specific temperature conditions.
