Patent number: 11286215Abstract: A cascade reactor scheme with acid and hydrocarbon flowing in reverse directions. The systems and processes for alkylation of olefins herein may include providing a first olefin to a first alkylation zone, and a second olefin to a second alkylation zone. Isoparaffin may be provided to the first alkylation zone. The isoparaffin and first olefin may be contacted with a partially spent sulfuric acid in the first alkylation zone to form a spent acid phase and a first hydrocarbon phase including alkylate and unreacted isoparaffin. The first hydrocarbon phase and second olefin may be contacted with a sulfuric acid feed in the second alkylation zone to form a second hydrocarbon phase, also including alkylate and unreacted isoparaffin, and the partially spent sulfuric acid that is fed to the first alkylation zone. Further, the second hydrocarbon phase may be separated, recovering an isoparaffin fraction and an alkylate product fraction.Type: GrantFiled: November 13, 2020Date of Patent: March 29, 2022Assignee: LUMMUS TECHNOLOGY LLCInventors: Zan Liu, Peter Loezos, Jackeline Medina, Romain Lemoine

Publication number: 20210395178Abstract: A process for the selective dimerization and etherification of isoolefins, including feeding a mixed C4 stream and an oxygenate stream to a first fixed bed reactor containing a first catalyst, producing a first reactor effluent comprising dimers of the isoolefin, unreacted C4s, and unreacted oxygenates. Feeding the first reactor effluent directly to a second fixed bed reactor containing a second catalyst, producing a second reactor effluent containing dimers of the isoolefin, unreacted C4s, and unreacted oxygenates. Feeding the second reactor effluent to a catalytic distillation reactor system containing a third catalyst. Concurrently in the catalyst distillation reactor system reacting unreacted C4s in the presence of the third catalyst to form additional dimers of the isoolefin and/or ethers, and separating the dimers of the isoolefins from unreacted oxygenates and unreacted C4s.Type: ApplicationFiled: October 31, 2019Publication date: December 23, 2021Applicant: LUMMUS TECHNOLOGY LLCInventors: Rosette Barias, Romain Lemoine

Patent number: 11198108Abstract: Producing C5 olefins from steam cracker C5 feeds may include reacting a mixed hydrocarbon stream comprising cyclopentadiene, C5 olefins, and C6+ hydrocarbons in a dimerization reactor where cyclopentadiene is dimerized to dicyclopentadiene. The dimerization reactor effluent may be separated into a fraction comprising the C6+ hydrocarbons and dicyclopentadiene and a second fraction comprising C5 olefins and C5 dienes. The second fraction, a saturated hydrocarbon diluent stream, and hydrogen may be fed to a catalytic distillation reactor system for concurrently separating linear C5 olefins from saturated hydrocarbon diluent, cyclic C5 olefins, and C5 dienes contained in the second fraction and selectively hydrogenating C5 dienes. An overhead distillate including the linear C5 olefins and a bottoms product including cyclic C5 olefins are recovered from the catalytic distillation reactor system.Type: GrantFiled: October 13, 2020Date of Patent: December 14, 2021Assignee: LUMMUS TECHNOLOGY LLCInventors: Yongqiang Xu, Peter Loezos, Willibrord A.
