Abstract
FIELD: oil refining. SUBSTANCE: heavy oil feedstock is refined in the presence of finely dispersed zeolite-containing catalyst with contacting temperature of feedstock and regenerated catalyst in ascending current at the first stage of 530-560 C and feedstock feed rate of 350-550 h. Obtained products are successively contacted at the second stage with catalyst used at the first stage in ascending current at 505-525 C and feedstock flow rate of 650-950 h, and then, in ascending current in fluidized bed of catalyst at 460-500 C. Fed to ascending current and fluidized bed of catalyst separately is cold heat carrier. These conditions increase yield of desired product by 3.4-4.9 mas.% due to exclusion of repeated cracking of feedstock and gasoline octane number by 1.5-2 n due to increase un it of isoparaffins. EFFECT: higher yield and quality of desired product of cracking. 2 dwg, 1 tbl
