    Abstract: The present invention provides a process for regenerating a catalyst for producing e-caprolactam comprising the steps of adsorbing a silicon compound on a zeolite catalyst that had been used for a Beckmann rearrangement reaction of cyclohexanone oxime and contacting the catalyst with an aqueous solution containing a compound selected from a quaternary ammonium compound, lower alkylamines and ammonia. The present invention also provides a process for producing e-caprolactam comprising subjecting cyclohexanone oxime to the Beckmann rearrangement reaction in the presence of the catalyst thus regenerated.
