Patent number: 5935415Abstract: A hydrocarbon feedstock is catalytically reformed in a sequence comprising a continuous-reforming zone, consisting essentially of a moving-bed catalytic reforming zone and continuous regeneration of catalyst particles, and a zeolitic-reforming zone containing a catalyst comprising a platinum-group metal and a nonacidic zeolite. The process combination permits higher severity, higher aromatics yields and/or increased throughput in the continuous-reforming zone, thus showing surprising benefits over prior-art processes, and is particularly useful in upgrading existing moving-bed reforming facilities with continuous catalyst regeneration.Type: GrantFiled: November 4, 1997Date of Patent: August 10, 1999Assignee: UOP LLCInventors: Robert S. Haizmann, John Y. G. Park, Michael B. Russ

Patent number: 5658453Abstract: A process combination is disclosed to selectively upgrade naphtha in a manner to obtain an aromatics-rich, low-olefin product from the combination. Preferably the naphtha is subjected to aromatization to obtain an aromatics concentrate which is upgraded by hydrogenation of olefins in the aromatics-rich stream. Olefin saturation is effected following separation of the major portion of hydrogen from the aromatics concentrate and before fractionation/stabilization for removal of light ends, with concomitant low saturation of aromatics and with removal of light ends in a fractionator which would be associated with the aromatization in any case.Type: GrantFiled: May 30, 1995Date of Patent: August 19, 1997Assignee: UOPInventors: Michael B. Russ, Aaron P. Kelly, John Y. G. Park

Patent number: 5401388Abstract: A process combination is disclosed to selectively upgrade naphtha to obtain gasoline which is in accordance with current standards for reformulated fuels. A naphtha feedstock is fractionated to selectively direct light naphtha to isomerization or blending, a head-cut fraction to reforming, and a heavy potion to selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy potion of the synthesis naphtha is processed by reforming. Light naphtha may be isomerized, with or without recycle of low-octane components of the product. A gasoline component is blended from light, synthesis, and reformate products from the process combination.Type: GrantFiled: September 7, 1993Date of Patent: March 28, 1995Assignee: UOPInventors: Robert J.

Patent number: 5399257Abstract: Hydrocarbon conversion processes having a susceptibility to coke formation on the internal surfaces of processing equipment are improved by inhibiting the formation of coke with the use of a glass bead treatment for the metal surfaces. After treating with ordinary glass bead cleaning methods, metal surfaces are found to inhibit coke formation. The glass bead treatment is easily performed and, therefore, offers advantages over other chemical treatments for the deposition of silica on reactor internals.Type: GrantFiled: November 30, 1993Date of Patent: March 21, 1995Assignee: UOPInventors: Michael B. Russ, Chi-Chu D. Low, Jeffry T. Donner

Patent number: 5389235Abstract: A combination downflow contaminant treatment and/or removal bed in combination with a radial flow bed of contaminant sensitive catalyst in a single reactor vessel eliminates unexpected deactivation of contaminant sensitive catalyst. The process of this invention also monitors the entrance of contaminants into the downflow contaminant treatment/removal bed to measure total contaminant loading to avoid unnecessary shut-downs of the reactor vessel during temporary contaminant loadings. This invention is particularly useful for highly sulfur sensitive reforming catalysts that are used in combination with a sulfur sorbent for removal of the sulfur contaminants.Type: GrantFiled: December 2, 1992Date of Patent: February 14, 1995Assignee: UOPInventors: Michael B. Russ, Thomas A. Jasonowicz

Patent number: 4795846Abstract: An improved dehydrocyclization process for the selective conversion of light hydrocarbons to aromatics is presented. The activity of a catalyst containing nonacidic L-zeolite is greatly enhanced by the addition of water, water precursors, or mixtures thereof to the reaction zone during the dehydrocyclization reaction. Addition of between 10 and 100 wt. ppm H.sub.2 O results in a higher product yield of aromatics with increased product octane.Type: GrantFiled: October 1, 1987Date of Patent: January 3, 1989Assignee: UOP Inc.Inventors: Joseph Zmich, Michael B.
