    摘要: This disclosure is concerned with the crystallization of ZSM-5 zeolites and, more particularly, is concerned with the preparation of high silica ZSM-5 zeolites having a silica-to-alumina ratio of greater than 70, up to and approaching infinity, by control of the pH so as to obtain rod-shaped crystals.
