FIELD: oil refining industry.
SUBSTANCE: present invention relates to oil refining industry, namely to processing of gasoline fractions, and can be used for production of gasoline fractions with high content of aromatic hydrocarbons with high output. Catalyst includes zeolite ZSM-5 modified with Zn, Fe and P and a matrix consisting of aluminium oxide and bentonite clay. Modified zeolite ZSM-5 contains 0.25-1 wt.% zinc oxide, 0.05-0.3 wt.% iron oxide and 0.05-4 wt.% phosphorus and has a lattice modulus SiO2/Al2O3 23-50. Content of components in the catalyst, wt.% is: modified zeolite ZSM-5 25-75; aluminium oxide 12.5-40; bentonite clay 12.5-35.
EFFECT: high output of the obtained gasoline fraction with high content of aromatic hydrocarbons.
