Patent number: 10722861Abstract: Reactor systems for use with ionic liquid catalyst. The reactor systems include one or more stages, which include a reactor and a heat exchanger, and a separation zone. The reactor and the heat exchanger may have a vertical orientation. Additionally, a separation vessel may also include a vertical orientation.

Patent number: 9914884Abstract: A process and apparatus uses a flash drum to separate light hydrocarbons from heavy oligomerate from an oligomerization zone. The heavy oligomerate can bypass a fractionation column in the oligomerate recovery section and be recycled to the oligomerization zone or other zones. Costs are saved by avoiding repeatedly transporting and processing the heavier recycled oligomerate.Type: GrantFiled: December 17, 2013Date of Patent: March 13, 2018Assignee: UOP LLCInventors: Charles P. Luebke, Clayton C. Sadler, Christian D. Freet

Patent number: 9914673Abstract: Disclosed is a process and apparatus for switching oligomerization feed between a first oligomerization zone that includes a uni-dimensional small pore zeolite to make more diesel and a second oligomerization zone that includes SPA catalyst for making more gasoline. The diesel can be recycled to make more propylene. The process and apparatus will provide refiners with flexibility to produce the most valuable product commensurate with fluctuating market conditions.Type: GrantFiled: November 8, 2013Date of Patent: March 13, 2018Assignee: UOP LLCInventors: Christopher P. Nicholas, Christian D. Freet, Steven L. Krupa, Kurt M. Vanden Bussche, Todd M. Kruse

Patent number: 9834492Abstract: Distillate cracks to propylene more readily than VGO. Additionally, less branched hydrocarbons crack to propylene more readily than more branched hydrocarbons. Oligomerization to diesel range oligomers followed by catalytic cracking with less branched oligomers can provide more propylene.Type: GrantFiled: November 8, 2013Date of Patent: December 5, 2017Assignee: UOP LLCInventors: Christopher P. Nicholas, Christian D. Freet, Kurt M. Vanden Bussche, Todd M. Kruse

Patent number: 9567267Abstract: A process provides oligomerization feed stream comprising C5 hydrocarbons and olefins along with C4 olefins to an oligomerization zone. The oligomerization feed stream may be obtained from cracked FCC products. Unreacted C5 hydrocarbons can be recycled to the oligomerization zone to maintain the liquid phase therein.Type: GrantFiled: November 8, 2013Date of Patent: February 14, 2017Assignee: UOP LLCInventors: Christopher P. Nicholas, Christian D. Freet, Steven L. Krupa, Kurt M. Vanden Bussche, Todd M. Kruse

Publication number: 20140170028Abstract: A process and apparatus are disclosed for recovering a product stream by fractionation perhaps with compression of a C5? hydrocarbon stream. The C5? hydrocarbon stream may be taken from an overhead of a fractionation column. Fractionation includes a depentanizer column followed by a depropanizer column for producing a C4 and C5 stream. The recovered product stream may be oligomerized to produce larger oligomers. Oligomers may be delivered to a cracking reactor which may produce the C5? hydrocarbon stream.Type: ApplicationFiled: December 14, 2012Publication date: June 19, 2014Applicant: UOP LLCInventors: Christian D. Freet, Todd M. Kruse, Christopher P. Nicholas
