CFI-type zeolite, process for preparation of the same, catalyst prepared from the same, and process for conversion of organic compounds

摘要

A CFI-type zeolite where the atomic ratio of silicon to the heteroatom is 45 or less and the long axes of the crystals are 0.7 mum or less is useful as a catalyst for conversion reaction of aromatic compounds because the zeolite has a number of active sites and small crystals.
