Title:
A HIGH PRODUCTIVE PROCESS FOR PRODUCTION OF LOWER OLEFINS BY CATALYTIC CONVERSION
Document Type and Number:
WIPO Patent Application WO/1995/012562
Kind Code:
A1
Abstract:
A process for production of lower olefins, especially propylene, isobutylene and isoamylene, and high octane number gasoline through catalytic conversion which comprises contacting the petroleum hydrocarbon with a solid catalyst for 0.1-6 second, at a temperature of 480-680 �C, a pressure of 1.2-4.0 x 105 Pa and catalyst-to-oil ratio of 4-20. The solid catalyst comprises phosphorus and rare-earth-containing high silica zeolite with the structure of a pentasil.
