Title:
FLUIDIZED CATALYTIC CONVERSION METHOD FOR PREPARING LOW-CARBON OLEFINS
Document Type and Number:
WIPO Patent Application WO/2022/147970
Kind Code:
A1
Abstract:
A fluidized catalytic conversion method for preparing low-carbon olefins, the method comprising the following steps: 1) introducing an olefin-rich raw material into a fluidized catalytic conversion reactor to be brought into contact with a catalyst at a temperature of 650°C or more for a reaction; 2) separating an oil and gas obtained from the reaction to obtain a stream containing C5 or higher olefins; and 3) returning at least part of the stream containing the C5 or higher olefins to step 1) for a continued reaction. The fluidized catalytic conversion method can effectively increase the yield of low-carbon olefins, improve the selectivity, and increase the ratio of ethylene/propylene in the product.
