Publication number: 20210308646Abstract: A fixed bed, radial flow reforming reactor having an inner catalyst zone between an inlet fluid zone and an outlet fluid zone. The catalyst zone is separated into two concentric, annular zones, a first annular zone having a first solid particle material having a first catalytic activity for reforming hydrocarbons into the catalyst zone, and, a second annular zone having a second solid particle material having a second catalytic activity for reforming hydrocarbons into the catalyst zone, wherein the second catalytic activity is different. One of the materials may be inert. A divider may be used to separate the two annular zones.Type: ApplicationFiled: March 11, 2021Publication date: October 7, 2021Inventors: Guy B.

Patent number: 7268267Abstract: A process for the alkylation of aromatics with olefins using a solid catalyst bed containing UZM-8 zeolite is disclosed. A polyalkylated aromatic is passed to the catalyst bed to reduce the concentration of the olefin at alkylation conditions. A portion of the effluent recovered from the catalyst bed may be recycled to the catalyst bed. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. The process disclosed herein is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.Type: GrantFiled: June 29, 2005Date of Patent: September 11, 2007Assignee: UOP LLCInventors: Deng-Yang Jan, James A.

Patent number: 6858769Abstract: A catalyst for the selective oxidation of hydrogen has been developed. It comprises an inert core such as cordierite and an outer layer comprising a lithium aluminate support.

Patent number: 6710003Abstract: A layered catalyst composition is disclosed where the composition is prepared by bonding an outer layer comprising a bound zeolite (e.g. zeolite beta) to an inner core material (e.g. cordierite). The use of an organic bonding agent in the catalyst preparation procedure provides a composition that is sufficiently resistant to mechanical attrition to be used commercially in aromatic alkylation processes (e.g. benzene alkylation to ethylbenzene). Advantages associated with the use of layered compositions include a significant reduction in the amount of zeolite used for a given reactor loading and improved selectivity to desired alkylated aromatic products. Further benefits are realized when the layered composition is formed into shapes having a sufficiently high void volume to reduce pressure drop across the alkylation catalyst bed. This is especially relevant for operation involving high recycle rates and consequently low alkylating agent concentrations in the reaction zone.Type: GrantFiled: December 13, 2001Date of Patent: March 23, 2004Assignee: UOP LLCInventors: Deng-Yang Jan, James F. Mc Gehee, Guy B. Woodle, Masao Takayama, Raelynn M. Miller

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.

Patent number: 6281399Abstract: A process for producing isopropyl aromatics using a transalkylation reaction zone and an alkylation reaction zone is disclosed. Portions of the transalkylation reaction zone effluent pass to a multibed alkylation reaction zone where aromatics in the transalkylation reaction zone effluent are alkylated to the desired isopropyl aromatics. At least a portion of the transalkylation reaction zone effluent passes to an alkylation bed other than the first alkylation bed of the multibed alkylation reaction zone. This process decreases the capital and operating costs of recycling the aromatics in the transalkylation reaction zone effluent. This process is well suited for solid transalkylation and alkylation catalysts. Cumene may be produced by this process.Type: GrantFiled: February 23, 2000Date of Patent: August 28, 2001Assignee: UOP LLCInventors: Russell C. Schulz, Gregory J. Gajda, Guy B. Woodle
