METHOD FOR PRODUCTION OF OLEFINS AND GASOLINE WITH LOW BENZENE CONTENT Russian patent published in 2016 - IPC C07C11/02 C07C4/06 C07C7/08 C07C4/04 C10L1/06 C10G9/36 C10G35/04 C10G55/04 C10G61/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for production of olefins and low benzene content gasoline from naphtha. Method involves the following steps: 1) subjecting naphtha to extractive distillation to obtain extract oil containing cycloalkane and aromatic hydrocarbon and raffinate oil containing alkane and C₆ cycloalkane, with mass ratio of C₆ cycloalkane in raffinate oil to C₆ cycloalkane in naphtha being 80-95 %, 2) contacting extract oil with a reforming catalyst in catalytic reforming reaction conditions: 0.01-3.0 MPa, 300-600 °C, a hydrogen/hydrocarbon mole ratio of 0.5-20, and a volume space velocity of 0.1-50 h^-1, thus obtaining reformate with a low benzene content; 3) sending raffinate oil into a steam cracking device to undergo cracking reaction to produce light olefins.

EFFECT: method leads to high degree of utilisation of naphtha and to production of petroleum component with low benzene content in addition to production of naphtha ethylene, propylene and butadiene with high output.
