METHOD OF PRODUCING LOWER OLEFINS FROM VACUUM GAS OIL Russian patent published in 1997 - IPC

Abstract RU 2099389 C1

FIELD: petroleum processing and petrochemistry. SUBSTANCE: vacuum gas oil is processed in two steps. In the first one, vacuum gas oil is subjected to heat cracking at 495-505 C, products being separated into light fraction with content of dark components not higher than 8% and heavy fraction. In the second step, light fraction (gas, gasoline, and, if necessary, kerosene-diesel fractions) is pyrolyzed at temperatures above 750 C. As a result, heavy part of heat cracking products (fraction above 500 C), which is low-grade raw material for pyrolysis, is withdrawn as component of furnace oil or raw material for coking process. EFFECT: increased yield of target product (lower olefins) and reduced coking process. 1 dwg , 2 tbl
