Title:
RESIDUAL OIL SLURRY BED HYDROCRACKING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/192788
Kind Code:
A1
Abstract:
A residual oil slurry bed hydrocracking method and device. A procedure of a "slurry bed + fixed bed" reactor is adopted, and raw materials, additives, catalysts and hydrogen gas are mixed, heated, pressurized and then fed into a slurry bed reactor for thermal cracking reaction and catalysis reaction. In the reaction process, coke, catalysts and additives are subsequently separated at the bottom of a thermal high pressure separator. A light oil product is produced through further hydrocracking and hydrogen refining in an ordinary fixed bed reactor. A ferro-molybdenum catalyst is adopted to improve the reaction activity, inhibit coke generation, reduce the pressure of the system to 17 to 20 MPa, and greatly lower the cost of equipment. By means of the method, the conversion rate of residual oil can be 90% to 95%, and the light oil yield can be 80% to 83%.
