Generally, an average bulk density of the catalyst is about 0.300-about 0.620 gram per cubic centimeter, and an atomic ratio of the lanthanide-series metal:noble metal is less than about 1.3:1. Moreover, the lanthanide-series metal can be distributed at a concentration of the lanthanide-series metal in a 100 micron surface layer of the catalyst less than about two times a concentration of the lanthanide-series metal at a central core of the catalyst.Type: GrantFiled: July 15, 2011Date of Patent: June 24, 2014Assignee: UOP LLCInventors: Mark Paul Lapinski, Paul Barger

Patent number: 8753503Abstract: One exemplary embodiment can be a process for producing a reformate by combining a stream having an effective amount of isopentane and a stream having an effective amount of naphtha for reforming. Generally, the naphtha has not less than about 95%, by weight, of one or more compounds having a boiling point of about 38-about 260° C. as determined by ASTM D86-07. The process may include introducing the combined stream to a reforming reaction zone. The combined stream can have an isopentane:naphtha mass ratio of about 0.10:1.00-about 1.00:1.00.Type: GrantFiled: July 24, 2008Date of Patent: June 17, 2014Assignee: UOP LLCInventors: Steven L.

Patent number: 8680351Abstract: A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.Type: GrantFiled: March 9, 2012Date of Patent: March 25, 2014Assignee: UOP LLCInventors: Manuela Serban, Antoine Negiz, Kurt M.

Patent number: 8658021Abstract: The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which the process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a final stage for further reforming at least a portion of the penultimate effluent 3) a regeneration step for the final stage catalyst. The severity of the penultimate stage can be increased during final stage catalyst regeneration in order to maintain the target RON of the reformate product and avoid reactor downtime.Type: GrantFiled: July 28, 2010Date of Patent: February 25, 2014Assignee: Chevron U.S.A.
