Patent number: 7452846Abstract: A desulfurization system employing a system of fluidizable and circulatable solid particles to desulfurize a hydrocarbon-containing fluid in a fluidized bed reactor. The solid particulate system includes solid sorbent particles operable to remove sulfur from the hydrocarbon-containing fluid stream and solid catalyst particles operable to enhance the octane of the resulting desulfurized hydrocarbon-containing fluid stream. The solid particulate system can be circulated between a reactor, regenerator, and reducer, to thereby allow for substantially continuous desulfurization in the reactor.Type: GrantFiled: May 22, 2007Date of Patent: November 18, 2008Assignee: China Petroleum & Chemical CorporationInventors: Edward L.

Patent number: 5024750Abstract: Heavy hydrocarbon oil, containing asphaltene, sulfur and metal contaminants, is hydrotreated in the presence of a hydrotreating catalyst having a small pore diameter in an initial process step to remove sulfur and metal contaminants. Removal of additional metal and sulfur contaminants is then accomplished in a second process step by solvent deasphalting, wherein the size of the pore diameter of the hydrotreating catalyst utilized in the initial hydrotreating step affects the metals rejection in the subsequent solvent deasphalting step. In a third process step the deasphalted oil is catalytically cracked substantially in the absence of added hydrogen to provide lower boiling hydrocarbon products.Type: GrantFiled: December 26, 1989Date of Patent: June 18, 1991Assignee: Phillips Petroleum CompanyInventors: Edward L. Sughrue, II, Patricia A. Tooley, Brent J. Bertus, Bille S. Grayson
