Abstract

FIELD: oil and gas processing; production of fuels. SUBSTANCE: processing of gas condensate includes separating gas from liquid phase, processing instable condensate obtained into motor fuels using catalytic refining and rectification processes, peculiar feature of which consists in that, to catalytic refining, instable condensate is directly subjected at 250-430 C and 0.1-1.5 MPa pressure followed by rectification producing desired fuel fractions. Process is preferably conducted in presence of zeolite-containing catalyst composed of (in wt %): Y-type zeolite with molar silica to alumina ratio 4-8, 0.05-5.0; high-silica zeolite with molar silica to alumina ratio 20-100, 0.05-85.0; matrix, the balance. Preferable volume velocity of raw material feeding is 0.5-3.5 cu.m/cu.m h. It is also desirable rectification process to be carried out in presence of either gases produced in the catalytic refining process or rectification gases. Method makes it possible to process gas condensate at oil field, to simplify essentially technology of gas condensate processing, to raise motor fuels' yield to 93.7% producing gasolines with octane number up to 85-98 and diesel fuels with cetane number 45-54, and, at last, to control yields of gasoline and diesel fractions. EFFECT: enhanced efficiency of process.

Usage: oil refining and petrochemical industry, namely the processing of gas condensate into motor fuels. The essence of the invention consists in the processing of gas condensate, including the separation of gas from the liquid phase, the processing of the obtained unstable condensate into motor fuels using catalytic refinement and rectification processes, while the unstable condensate is directly treated in the presence of a zeolite-containing catalyst at a temperature of 250-430 o C, pressure 0 , 1 - 1.5 MPa, after which the catalysis is subjected to rectification with the selection of the target fuel fractions. It is advisable to carry out the process in the presence of a zeolite-containing catalyst having the following composition, wt.%: Type U zeolite with a molar ratio of SiO 2 / Al 2 O 3 equal to from 4.0 to 8.0, - 0.05 - 5.0, high silica zeolite with a molar ratio of SiO 2 / Al 2 O 3 equal to from 20 to 100, - 0.05 - 85.0, the matrix - the rest. The process is preferably carried out at a volumetric feed rate of 0.5 to 3.5 m 3 / (m 3 • h). It is also desirable to carry out the catalytic rectification process in the presence of gaseous products formed during the catalytic refinement and / or rectification gases. The proposed method allows for the processing of gas condensate in the field, significantly simplify the technology of processing gas condensate, increase the yield of motor fuels to 93.7 wt.% With the production of gasolines with an octane rating of 85 to 98 and diesel fuels with a cetane number of 45 - 54, and also regulate output of gasoline and diesel fractions.
