プロピレンの製造方法
Document Type and Number:
Japanese Patent JP5116043
Kind Code:
B2
Abstract:
An object of the present invention is to provide a process for producing efficiently and stably propylene from a hydrocarbon raw material containing a high concentration of ethylene. The present invention discloses a process for producing propylene, comprising catalytically converting a hydrocarbon raw material containing ethylene in an amount exceeding 50% by mass with a zeolite-containing catalyst satisfying the following (1) to (3):
(1) containing of a medium pore diameter zeolite having a pore size of from 5 to 6.5 Å;
(2) a SiO 2 /Al 2 O 3 molar ratio in the medium pore diameter zeolite being from 20 to 300; and
(3) an acid amount (TPD acid amount), determined by a high-temperature desorption amount in an ammonia temperature-programmed desorption spectrum, being from 20 to 350 µmol/g-zeolite.
