US Patent:

53169921, May 31, 1994

Filed:

Nov 13, 1992

Appl. No.:

7/976158

Inventors:

Michael B. Russ - Villa Park IL
Paul A. Sechrist - Des Plaines IL

Assignee:

UOP - Des Plaines IL

International Classification:

B01J 2932
B01J 2936

US Classification:

502 66

Abstract:

A catalyst system comprises a physical mixture of a conversion catalyst and a sulfur sorbent to accommodate small quantities of sulfur from a hydrocarbon feedstock. Preferably, the physical mixture comprises a sulfur-sensitive reforming catalyst protected from sulfur deactivation by a manganeseoxide catalyst. The invention shows substantial benefits over prior-art processes in catalyst utilization.

Assignee:

UOP - Des Plaines IL

International Classification:

C10G 5906

US Classification:

208 78

Abstract:

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 heart-cut fraction to reforming, and a heavy portion to selective isoparaffin synthesis to yield light and heavy synthesis naphtha and isobutane. The heavy portion 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.

International Classification:

C10G 3504

US Classification:

208134

Abstract:

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.

Appl. No.:

8/453604

Michael B. Russ - Villa Park IL

John Y. G. Park - Naperville IL

Assignee:

UOP - Des Plaines IL

International Classification:

C10G 6302

US Classification:

208 62

Abstract:

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.

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

C10G 3506
C07C 252

US Classification:

585417

Abstract:

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.

Assignee:

UOP LLC - Des Plaines IL

International Classification:

C10G 3506

US Classification:

208 64

Abstract:

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.

International Classification:

C10G 3509

US Classification:

208138

Abstract:

A sacrificial particulate bed is utilized to remove contaminants, such as sulfur, from a conversion system. Subsequently, the sacrificial particulate bed is replaced by a contaminant-sensitive catalyst, such as a reforming catalyst selective for dehydrocyclization.

US Classification:

208 65

Abstract:

A hydrocarbon feedstock is catalytically reformed to effect dehydrocyclization of paraffins in a process combination comprising a first reforming zone containing a mixed reforming catalyst and sulfur sorbent and a sulfur-removal zone utilizing a manganese component to preclude sulfur from the feed to a second reforming zone. The process combination shows substantial benefits over prior art processes in achieving reforming-catalyst stability.
