Title:
AUXILIARY AGENT FOR REDUCING OIL SLURRY AND INCREASING YIELD OF LOW-CARBON OLEFINS, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/043017
Kind Code:
A1
Abstract:
An auxiliary agent for reducing oil slurry and increasing the yield of low-carbon olefins, the relative dry basis content of the raw materials being as follows: 40-55wt% of a phosphorus-containing MFI molecular sieve, 0-10wt% of a macroporous molecular sieve, 3-20wt% of an inorganic binder, 8-22wt% of an inorganic matrix and 15-40wt% of clay. The described auxiliary agent is used in catalytic cracking, and may improve the yield of cracked liquefied gas, increase the concentration of propylene in liquefied gas, increase the octane number of catalytically cracked gasoline and reduce the yield of oil slurry in a cracked product.
