Patent number: 10899683Abstract: A process for producing ethylbenzene is described in which benzene and ethylene are supplied to an alkylation reaction zone. Also added to the alkylation reaction zone is a C3+ olefin in an amount of at least 200 ppm by weight of the ethylene supplied to the alkylation reaction zone. The benzene, ethylene and C3+ olefin are contacted with an alkylation catalyst in the alkylation reaction zone to alkylate at least part of the benzene and produce an alkylation effluent comprising ethylbenzene, polyethylated benzene and at least one mono-C3+ alkyl benzene. The alkylation effluent is separated into a first product fraction comprising ethylbenzene and a second fraction comprising polyethylated benzene and the at least one mono-C3+ alkyl benzene. The second fraction is then contacted with benzene in the presence of a transalkylation catalyst to convert at least part of the polyethylated benzene to ethylbenzene and produce a transalkylation effluent.Type: GrantFiled: February 17, 2016Date of Patent: January 26, 2021Assignee: BADGER LICENSING LLCInventors: Brian Maerz, Chung-Ming Chi, Raghavender Bhoomi

Patent number: 10280128Abstract: In a process for alkylating an aromatic hydrocarbon feedstock with an olefin feedstock, at least one of the aromatic hydrocarbon and olefin feedstocks is passed through a pretreatment unit containing an adsorbent such that the adsorbent removes impurities contained by the feedstock. Passage of the at least one feedstock through the pretreatment unit is then terminated and a heated inert gas is passed through the pretreatment unit such that the inert gas desorbs impurities from the adsorbent to produce an inert gas effluent stream containing the desorbed impurities. A condensable fluid is added to at least part of the inert gas effluent stream such that at least a portion of the impurities contained therein condense with said fluid to leave a purified inert gas stream, which is recycled to the pretreatment unit.Type: GrantFiled: July 25, 2013Date of Patent: May 7, 2019Assignee: BADGER LICENSING LLCInventors: Brian Maerz, Douglas Hubbell, Maruti Bhandarkar, Vijay Nanda
