FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil refining industry, namely to method of obtaining high-octane motor petrol. Invention deals with method for obtaining motor petrol, which involves separation of petrol distillate of catalytic cracking into light and heavy fractions, hydroforming of heavy fraction mixed with straight-run diesel fraction, further additional hydroforming of extracted hydrotreated petrol fraction mixed with straight-run petrol fraction. Extracted hydrotreated petrol fraction is separated into two parts, one of which is subject to additional hydroforming mixed with straight-run petrol fraction; after that, it is directed to catalytic reforming, and the other part is mixed with light fraction of petrol distillate of catalytic cracking and catalysate of catalytic reforming in the following ratio, % wt: 20:40:40-10:30:60 respectively so that commercial motor petrol is obtained.
EFFECT: compliance of base components of high-octane motor petrols as to quality with European standards.
