Title:
プロピレンの製造方法
Document Type and Number:
Japanese Patent JP5607024
Kind Code:
B2
Abstract:
The present invention provides in a method for producing propylene from a hydrocarbon raw material containing ethylene in an amount exceeding 50% by mass under the co-existence of water, a method for producing propylene stably over a long term from ethylene in a high yield and with the reaction/regeneration repeated. A method for producing propylene includes a step for catalytically converting a hydrocarbon raw material containing ethylene in an amount exceeding 50% by mass with a zeolite-containing catalyst while supplying water, wherein a zeolite contained in the zeolite-containing catalyst satisfies (1) to (3) shown below; (1) the zeolite is an MFI zeolite, (2) a zeolite crystallization index obtained from an X-ray diffraction spectrum is 3.3 or more, and (3) a molar ratio of silica/alumina (SiO2/Al2O3) is 20 to 300.
