Patent number: 8092671Abstract: A method is disclosed for treating gaseous effluent from a hydrocarbon pyrolysis unit to provide steam cracked tar of reduced asphaltene and toluene insolubles content. The method is suitable for preparing reduced viscosity tar useful as a fuel blending stock, or feedstock for producing carbon black, while reducing or eliminating the need for externally sourced lighter aromatics additives to meet viscosity specifications. The method comprises drawing steam cracked tar from a separation vessel, e.g., a primary fractionator or tar knock-out drum, cooling the tar, and returning it to the separation vessel to effect lower overall tar temperatures within the separation vessel, in order to reduce viscosity increasing condensation reactions. An apparatus for carrying out the method is also provided.Type: GrantFiled: December 21, 2009Date of Patent: January 10, 2012Assignee: ExxonMobil Chemical Patents, Inc.Inventors: Robert David Strack, Richard C.

Patent number: 8062506Abstract: An FCC process comprising an enlarged riser section and a distributor in an elevated position and with an opening in its tip away from riser walls may reduce coke build-up along the interior walls of a riser. Catalytic mixing may be improved, which could reduce riser coking by increasing hydrocarbon contact with catalyst before contacting the riser wall. Increasing the distance between the introduction of the hydrocarbon and the riser wall may increase this likelihood for hydrocarbon-catalyst contact. Highly contaminated hydrocarbons cause greater coking than do normal hydrocarbons and this FCC process may be effective in decreasing riser coking on such heavy hydrocarbons.Type: GrantFiled: June 14, 2010Date of Patent: November 22, 2011Assignee: UOP LLCInventors: Brian W.
