International Classification:

C07C 51114

US Classification:

562521, 562522, 560232, 560233, 585654, 585655

Abstract:

Long chain alcohols and acids or other similar oxygenates such as esters are produced from paraffins of similar carbon number by a process comprising paraffin dehydrogenation, carbonylation, and separation. Preferably a mixture of paraffins extending over several carbon numbers and recovered from a kerosene fraction is processed, and unconverted paraffins are recycled to a dehydrogenation zone. Alternative reaction zone configurations, catalyst systems and product recovery methods are disclosed.

International Classification:

C07C 51/14

US Classification:

562522, 562521

Abstract:

A catalyst useful for carbonylation of olefins has been developed. The catalyst comprises a palladium compound, e. g. PdImCl, where Im is imidazole and HCl dissolved in water or an alcohol. Carbonylation using this catalyst involves contacting an olefin stream preferably in a solvent such as o-xylene with the catalyst and carbon monoxide at carbonylation conditions to provide a carboxylic acid or an ester. When the catalyst solvent is water one can obtain an acid as the product, but when the catalyst solvent is an alcohol one obtains an ester as the product.

International Classification:

A63C 1904

US Classification:

472 92

Abstract:

The present invention provides a portable and expandable track or velodrome 10 for racing bicycles indoors and outdoors. The portable velodrome 10 includes a support structure network 18 that circumscribes an infield area 12 and a plurality of modular track surface sections 30 removably mounted on the support structure network 18 to form a banked track 22 having a racing surface. The modular track sections 30 are mounted on the support structure network 18 with track section mounting elements that do not interrupt the racing surface. The portable velodrome 10 further includes a substantially horizontal track section 28 extending from a bottom of the banked track 22 toward the infield area 12, and a transition surface between the banked track 22 and the horizontal track 28.

Inventors:

Robert H. Jensen - Clarendon Hills IL

Assignee:

UOP Inc. - Des Plaines IL

International Classification:

B01J 802
C10G 1110

US Classification:

208146

Abstract:

Distribution of a mixed-phase, vapor/liquid reactant stream to a fixed-bed of catalyst particles is accomplished through the use of a distributor tray in the form of a horizontal plate (or deck) having a plurality of vertically-disposed venturi-shaped eductors. The distributing device is installed within a substantially catalyst-free area of the reaction chamber and serves (i) to initially distribute the reactant stream as a froth to the reaction chamber and/or, (2) to distribute the effluent from one bed of catalyst particles to the next succeeding bed of catalyst particles.

US Classification:

502325

Abstract:

This invention relates to a layered catalyst composition, a process for preparing the composition and processes for using the composition. The catalyst composition comprises an inner core such as alpha-alumina, and an outer layer bonded to the inner core composed of an outer refractory inorganic oxide such as gamma-alumina. The outer layer has uniformly dispersed thereon a platinum group metal such as platinum and a promoter metal such as tin. The composition also contains a modifier metal such as lithium. The catalyst composition shows improved durability and selectivity for dehydrogenating hydrocarbons.
