PROCESS FOR FRAGMENTING A SHAPED ARTICLE OF ZEOLITE

摘要

PURPOSE: A shaped zeolite product fragmentation method is provided to obtain zeolite, which is suitable for re-shaping processes, and to prevent the crystallinity of the zeolite from being reduced. CONSTITUTION: A shaped zeolite product fragmentation method includes a process in which shaped zeolite products are in contact with a basic aqueous solution containing 2 weight% or more of quaternary ammonium. The shaped zeolite products are pentasyl type shaped zeolite products. The quaternary ammonium is tetraalkyl ammonium. The shaped zeolite products are used for the catalyst of the Beckmann rearrangement reaction of cyclohexanone oxime.
