METHOD FOR PROCESSING HEAVY OILS Russian patent published in 2023 - IPC C10G11/02 B01J27/22 B01J23/26 B01J23/755 B01J21/04 

FIELD: oil refining.

SUBSTANCE: invention relates to the field of oil refining, namely the processing of heavy oil, and can be used to obtain gasoline and diesel fractions. The invention relates to a method for processing heavy oils into gasoline and diesel fractions by catalytic cracking at a temperature of 450°C for 100 minutes is carried out in the presence of amorphous aluminosilicate and a modifier consisting of a mixture of nichrome and tungsten carbide at a ratio of 3:1, taken in an amount of amorphous aluminosilicate from 0.1 to 3.0 wt.% by weight of oil and modifier 0.5-2.0 wt.% from the mass of amorphous aluminosilicate.

EFFECT: increase in the yield of gasoline (NK-200°C) and diesel (200-360°C) fractions up to 27.2 and 45.9 wt.% respectively, and slowing down the coking of amorphous aluminosilicate by 2.5-3 times with the help of preliminary modification.
