METHOD OF OBTAINING AUTOMOBILE PETROL Russian patent published in 2016 - IPC C10G35/04 

FIELD: chemistry.

SUBSTANCE: method includes catalytic reforming of straight-run hydro-purified petrol fraction with preliminary separation of petrol part of reaction mixture and separation of catalytic reforming catalysate. Petrol part of reaction mixture is preliminarily divided by fractioning into main, medium and residual fractions, which boil out in the interval of temperatures 62-85°C, 85-100°C and 100-190°C respectively, residual fraction is subjected to catalytic reforming, catalytic reforming catalysate is divided into low-boiling and high-boiling fractions, which boil out in the interval of temperatures i.b.-90°C and 90°C-e.b. respectively, and in process of blending involved is head of stabilisation i.b.-62°C, low-boiling fraction i.b.-90°C, high-boiling fraction 90°C-e.b. with addition of methyltertbutyl ether.

EFFECT: method makes it possible to obtain automobile petrol with reduced content of benzene, improve technological efficiency of reforming process with preservation of high anti-detonation characteristics of fuel.
