    摘要： The present invention relates to a process for regenerating a catalyst for the cyclizing hydrolysis of an aminonitrile for the manufacture of lactams. It relates more particularly to the regeneration of the solid catalysts used in the processes for producing lactams by the cyclizing hydrolysis of aminonitriles. This regeneration process consists in treating the spent catalyst or the catalyst at the end of the cycle at a temperature of between 300° C. and 600° C. with an oxidizing atmosphere.
