MFI TYPE ZEOLITE, CATALYST INCLUDING MFI TYPE ZEOLITE, AND METHOD FOR PRODUCING LOWER OLEFIN USING CATALYST

摘要

PROBLEM TO BE SOLVED: To provide: a new MFI type zeolite containing very fine phosphorus whose particle size is 10 to 200 nm; a catalyst comprising the MFI type zeolite, and having both a long lifetime and high selectivity; and to provide a method for synthesizing a lower olefin from ethanol by using the catalyst.SOLUTION: An MFI type zeolite whose particle size is 10 to 200 nm and whose P/Al mol ratio is 0.2 to 1.0, and a catalyst including the MFI type zeolite are provided. A lower olefin is synthesized from at least one selected from a group comprising ethanol, ethylene and diethyl ether by using the catalyst.
