FIELD: technological processes.
SUBSTANCE: invention relates to a method of processing natural bitumen into gasoline and diesel fractions by catalytic cracking in medium of acetylene in presence of mesoporous aluminosilicate with pore diameter of 50 Ǻ, taken in amount of 5-10 wt%, modified by nanosized powder of nickel with mean particle size of 20 nm, produced by gas-phase synthesis, in an amount of 0.5-2.0 % to weight of zeolite. As a result, output of gasoline (NK-200 °C) increases to 23.9 % and output of diesel (200-360 °C) fractions increases to 42.7 % with reduction of gas and new growth to 3.2 and 0.2 wt%, respectively.
EFFECT: increased output of gasoline and diesel fractions.
