Patent number: 6339179Abstract: A process for producing alkyl aromatics using a transalkylation reaction zone and an alkylation reaction zone is disclosed. One portion of the transalkylation reaction zone effluent passes to an alkylation reaction zone where an aromatic substrate is alkylated to the desired alkyl aromatic. At least a portion of the alkylation reaction zone effluent and another portion of the transalkylation reaction zone effluent pass to a product recovery zone. This process decreases the capital and operating costs of recycling aromatic substrate to the transalkylation and/or alkylation reaction zone while maintaining operational flexibility. This process is well suited for solid transalkylation and alkylation catalysts. Ethylbenzene and cumene may be produced by this process.Type: GrantFiled: July 25, 2000Date of Patent: January 15, 2002Assignee: UOP LLCInventors: Russell C. Schulz, Gregory J. Gajda, Guy B. Woodle, Andrew S. Zarchy

Patent number: 6303839Abstract: The present invention relates to a process for the production of light olefins comprising olefins having from 2 to 4 carbon atoms per molecule from an oxygenate feedstock. The process comprises passing the oxygenate feedstock to an oxygenate conversion zone containing a metal aluminophosphate catalyst to produce a light olefin stream. A propylene stream and/or mixed butylene is fractionated from said light olefin stream and cracked to enhance the yield of ethylene and propylene products. This combination of light olefin product and propylene and butylene cracking in a riser cracking zone or a separate cracking zone provides flexibility to the process which overcomes the equilibrium limitations of the aluminophosphate catalyst. In addition, the invention provides the advantage of extended catalyst life and greater catalyst stability in the oxygenate conversion zone.Type: GrantFiled: June 14, 2000Date of Patent: October 16, 2001Assignee: UOP LLCInventor: Terry L. Marker

Patent number: 6194625Abstract: Disclosed are various embodiments for alkylating olefins and isoparaffins in the presence of an acid to reduce and/or control acid consumption or maximize and/or control the octane number of the produced alkylate product. One embodiment includes alkylation by controlling the C3/iso-C5 olefin ratio to reduce acid consumption. Another embodiment includes alkylation of C3 and C5 olefins in separate alkylation zones to maximize alkylate octane number. Even another embodiment includes propylene alkylation followed by C4 and/or C5 olefin alkylation, with the spent propylene acid used in the C4 and/or C5 olefin alkylation. Still another embodiment includes alkylation of C3, C4 and C5 olefins in separate alkylation zones, with the spent propylene acid used in the C4 alkylation, and the spent butylene acid used in the C5 alkylation. Yet another embodiment includes alkylation by controlling the C3/C4 olefin ratio to maximize the octane number of the produced alkylate.Type: GrantFiled: September 22, 1998Date of Patent: February 27, 2001Assignee: Stratco, Inc.Inventors: David C. Graves, Ken Edward Kranz, James Kevin Millard, Lyle Frederick Albright

Patent number: 6150578Abstract: A separation arrangement for a cumene process that operates with a relatively wet feed to an alkylation zone and relatively dry feed to a transalkylation zone reduces utilities and capital expenses for the separation and recycle of distinct wet and dry components by using an arrangement that first separates effluent from the trans alkylation and alkylation reaction zone in a benzene column before performing light ends and drying in a downstream depropanizer column. The arrangement uses a portion of the net overhead stream from the benzene column as a wet recycle stream for return to the alkylation reaction zone and sends another portion of the benzene net overhead to the depropanizer to supply a dry benzene recycle for the trans alkylation reaction zone.Type: GrantFiled: December 7, 1999Date of Patent: November 21, 2000Assignee: UOP LLCInventors: Perry K. Ho, Russell C. Schulz
