FIELD: oil and gas industry.
SUBSTANCE: disclosed is a catalyst for co-cracking petroleum fractions, which includes zeolite ZSM-5, ultra stable zeolite HPZEY and a matrix consisting of amorphous aluminosilicate, aluminum oxide and bentonite clay, where zeolite ZSM-5 has Si/Al ratio of 30 to 80, contains from 2.0 up to 4.0 wt% phosphorus, at following ratio of components in catalyst, wt%: phosphorus-modified zeolite ZSM-5 8–20; ultra-stable zeolite HPZEY 15–25; aluminum oxide 15–30; bentonite clay 15–30, and amorphous aluminosilicate 16–30.
EFFECT: obtaining a highly active catalyst for joint cracking of petroleum fractions, which provides high output of light olefin hydrocarbons.
