METHOD OF PROCESSING OIL AND GAS CONDENSATE Russian patent published in 2010 - IPC C10G7/00 C10G15/12 C10G57/00 C10G2/00 

FIELD: chemistry.

SUBSTANCE: invention relates to oil processing and specifically to a method of processing oil and/or gas condensate to obtain engine fuel. The invention relates to a method of processing oil and/or gas condensate, involving a step for fractionating the initial material with extraction of straight-run petrol, diesel and residual fractions or petrol, kerosene and residual fractions, or naphtha and residual fractions, and possibly hydrocarbon gases, subsequent high-temperature processing of the residual fraction, possibly in a mixture with gaseous hydrocarbons, through vapour and/or vapour-oxygen and/or vapour-carbon dioxide gasification to obtain synthetic gas. The obtained synthetic gas is converted to oxygen-containing products, including crude methanol, at high temperature and excess pressure on a copper-containing catalyst. The straight-run naphtha or straight-run petrol fraction, together with the oxygen-containing products, are brought into contact at temperature of 300-480°C and pressure of 2-40 atm with a catalyst which contains ZSM-5 or ZSM-11 zeolite, including that which is modified with group I, II, III, V, VI and VIII elements, separation of the contacting products with extraction of gaseous fractions and the end high-octane petrol fraction. The straight-run kerosene or diesel fraction is obtained as an end product or undergoes hydrofining to obtain an end product.

EFFECT: increased output of light petroleum products to 90 wt %, wide range of products.
