Abstract: Rhenium is recovered in a substantially pure form from a hydrochloric acid solution thereof contaminated with molybdenum and iron by adding sulfuric acid to establish a sulfate/chloride anion ratio of at least 20:1 and mixing the solution with a liquid trialkyl phosphate to extract rhenium in the phosphate phase. The trialkyl phosphate phase is seaprated and washed with sulfuric acid to remove any residual iron and molybdenum and thereafter with hydrochloric acid to remove entrained sulfuric acid. Rhenium is recovered by back extracting with nitric acid.

Abstract: Dehydrogenatable hydrocarbons are dehydrogenated by contacting them, at dehydrogenation conditions, with a catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a Group IB transition metal component, a rhenium component and a tin component with a porous carrier material. A specific example of the catalytic composite disclosed herein is a combination of a platinum group component, a Group IB component, a rhenium component, a tin component and an alkali or alkaline earth component with a porous carrier material wherein substantially all of the platinum group component, the Group IB component and the rhenium component are present as the corresponding elemental metals and substantially all of the tin component is present in an oxidation state above the elemental metal, and wherein the composite contains about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 5 wt. % Group IB metal, about 0.01 to about 2 wt. % rhenium, about 0.01 to about 5 wt.

Abstract: Additive formulations for use in petroleum distillates such as gasoline which provide improved properties will comprise a mixture of a solution of the polymeric reaction product between an epihalohydrin and an N-alkyl polyamine in an aromatic solvent, a solution of the polymeric reaction product of an epihalohydrin and a primary amine in an aromatic solvent, a lower molecular weight alcohol and a demulsifier.

Abstract: In a process for producing alkylaromatics by halogenating a paraffin and reacting the halogenated paraffin with an aromatic hydrocarbon, the rate of halogenation is improved by treating the n-paraffin to selectively remove oxygen-containing hydrocarbonaceous compounds from the n-paraffin with a sorbent selective for such oxygen-containing compounds, and subsequently halogenating the treated n-parffin. The improvement is particularly useful in producing alkylaromatic hydrocarbons from monocyclic aromatic compounds and n-paraffins.

Abstract: Portable, self powered water pumping apparatus for use in sampling water in remotely located wells comprises a wheeled hose reel cart which supports a long length of plastic hose or tubing. The tubing has a small diameter length of inner tubing telescoped inside itself throughout most of its length. The inner tubing passes through the wall of the outer tubing near the upper end thereof and is connected to a pressurized cylinder of gas such as a standard 14 oz. propane gas cylinder. When the lower ends of the tubes are well submerged beneath the water level in a well, admission of gas to the inner tube at its upper end will force water up through an annular space between the tubes and out the upper end of the outer tube where it can be collected. A channeled plug at the bottom of the tubes prevents the tubes from collapsing, helps to keep them straight and together as they are lowered into the well and provides partial support for a weight hanging from the bottom of the tubes.

Abstract: An electric lamp bulb type of heat furnishing unit is provided with a covering of active oxidation catalyst such that fumes and odors in the confines of a room that are drawn over the catalytic surface will be converted to less objectionable products. A light bulb type of catalyst supporting device is of particular advantage in that it can readily be screwed into a lamp base or other form of current supplying receptacle and, in addition, will provide a hot surface for inducing natural air convection current flow past the catalytic surface. Various types of coatings and/or catalytic wrappings may be used on the bulb to provide any particular type or form of catalytic surface.

Abstract: An improved combination process for the production of an unleaded, narrow boiling range, high octane motor fuel which involves (1) a novel form of low-severity hydrocracking followed by (2) catalytic reforming wherein the exothermic conversion in the hydrocracking zone is controlled by adjusting the hydrocracking reaction zone pressure. The process is effected without the intermediate separation of the product effluent from the low-severity hydrocracking zone, and therefore, provides a true "in-line" hydrocracking/reforming combination process.

Abstract: Nuclear hydroxylation of aromatic compounds is effected by treating said aromatic compounds with hydrogen peroxide in the presence of a catalyst comprising an alkaline solution containing a salt of hydrocyanic acid, or an aromatic or aliphatic nitrile compound.

Abstract: A method of impregnating a catalytic component as a subsurface layer on a carrier material. The carrier material is immersed in an impregnating solution containing a catalytic component and a dibasic carboxylic acid, with a sulfur-containing carboxylic acid being subsequently added to the solution whereby the catalytic component is dispersed in a subsurface layer on the carrier material and penetration beyond the desired subsurface layer is substantially obviated.

Abstract: The normal paraffin feed stream to an integrated paraffin isomerization-HF acid-catalyzed alkylation process is treated for the removal of catalyst deactivating sulfur and nitrogen compounds and water by contacting the feed stream with liquid hydrofluoric acid. The treated feed stream is separated from the acid by gravity settling, charged to an alkylate fractionator, and passed through the isomerization process to form an isomerate which is returned to the alkylate fractionator and becomes a feed stream to the alkylation zone.

Abstract: A catalytic composite, comprising a combination of a nickel component and a tungsten component with a silica-alumina carrier material wherein said carrier material is co-gelled silica-alumina consisting of from about 43 percent to about 57 percent by weight of alumina and from about 57 percent to 43 percent by weight silica and wherein said components are present in amounts sufficient to result in the composite containing, on an elemental basis, about 2 to about 10 percent by weight of the nickel component and about 8 to about 20 percent by weight of the tungsten component, is disclosed. Key features of the subject composite are the criticality of the alumina content of the carrier material and the facility of using a co-gelled silica-alumina carrier material. The principal utility of the subject composite is in the hydrocracking of hydrocarbons.

Abstract: Novel compositions of matter which are useful as biodegradable detergents comprise alkali metal disubstituted cyclohexenyl sulfates. These compounds are prepared by condensing butadiene with allyl chloride, thereafter ring alkylating the resultant chloromethylcyclohexene with an olefin in the presence of a free-radical generating compound and reacting the disubstituted cyclohexene with an alkali metal salt of a sulfur-containing compound to form the desired product.
