METHOD OF PROCESSING PETROLEUM DISTILLATES

摘要

The invention relates to petroleum chemistry, in particular to method for producing high-octane gasoline fractions from straight petrol distillates. T he inventive method for processing petrol distillates into gasoline fractions having an end boiling point equal to or less than 195 ~C and an octane numbe r equal to or greater than 80 according to a motor method, consists in transforming a hydrocarbon material in a presence of a porous catalyst at a temperature ranging from 200 ~C to 250 ~C, a pressure equal to or less than 2 MPa and mass rates of a hydrocarbon mixture equal to or less than 10 h-1. Ceolite having an alumosilicate composition modified by metals having silica te or alumophosphate compositions is used as a catalyst. The inventive method makes it possible to simplify the process and increase the production of hig h- octane gasoline fractions using the straight petrol distillates having an extended hydrocarbon composition as a feed stock, said distillates not being pre-fractionated and cleaned from sulphur-containing combinations.
