Abstract: A process for converting hydrocarbons with stabilized crystalline aluminosilicate catalysts. The catalysts contain zinc, and are stabilized by adding thereto another metal of Group IB or Group VIII (e.g. copper or nickel). Germanium, rhenium and the rare earth metals may also be added.

Abstract: An improved process using a rare earth-containing catalyst is provided. The catalyst comprises a composite of matrix and rare earth or of zeolite, rare earth and matrix, usually alumina. The rare earth can be a single metal or a mixture of rare earth metals. The process involved is the conversion of alcohols or ethers to gasoline boiling range hydrocarbons.

Abstract: Compounds that act as emulsifiers, detergents and antioxidants when added to a lubricant or a fuel are prepared from (1) an alkenylsuccinic anhydride or acid and an aniline-aldehyde resin or (2) the product of (1) and an aromatic triazole, e.g. benzotriazole, and aldehyde. Also included are lubricant compositions containing the compounds.

Abstract: A method is disclosed for synthesizing a crystalline aluminosilicate zeolite containing an organic nitrogen cation in the presence of a primary monoalkylamine having 2 to 9 carbon atoms in the alkyl portion. The method produces a zeolite having a very low percentage, i.e. less than about 0.14 weight percent, generally less than about 0.1 weight percent of alkali metal, e.g. sodium, in the as-synthesized form. The product can be used directly as a catalyst without intermediate precalcination and cation exchange. This is not possible with zeolites such as those of the ZSM-5 type synthesized by the methods of the art.

Abstract: A catalytic process is provided for converting a feed containing a C.sub.1 -C.sub.4 monohydric alcohol by contact of said alcohol, under conversion conditions, with a catalyst comprising a crystalline aluminosilicate zeolite having a crystal size of at least about 1 micron, a silica to alumina ratio of at least about 12 and a constraint index, as hereinafter defined, within the approximate range of 1 to 12. The zeolite contains a Group 2B and a Group 8 metal or metal compound plus magnesium, either per se or in compound form.

Abstract: Aluminosilicate zeolites are prepared containing an outer aluminum-free shell. The outer shell is essentially SiO.sub.2 that has crystallized on the zeolite surface in the ZSM-5 type configuration, leading to a more selective catalyst.

Abstract: Crystalline aluminosilicate zeolites are mixed with conventional reforming catalysts to produce new catalytic compositions with high catalytic activity and selectivity and excellent aging characteristics. These new catalytic compositions may be utilized alone or in conjunction with conventional reforming catalysts. The acidic activity of the total catalyst system is controlled within defined limits. When so controlled the utility of these catalyst systems in reforming hydrocarbon mixtures is to reduce the C.sub.1 and C.sub.2 concentrations in reformer gas product, while increasing the C.sub.3 and C.sub.4 concentrations and maintaining high liquid yield at high octane numbers.

Abstract: A process for removing phosphate ore from siliceous materials using a material comprising a combination of a sulfonated hydrocarbon and a kerosene.

Abstract: Crystalline aluminosilicate catalysts, especially those containing zinc, are stabilized with respect to elution of the zinc by adding thereto another metal of Group IB or Group VIII (e.g. copper or nickel). Germanium, rhenium and the rare earth metals may also be added.

Abstract: The invention provides a titania-zirconia or a titania-zirconia-alumina catalyst base containing a system of metals, metal oxides or metal sulfides from Groups VIB and VIII of the Periodic Table. Such catalysts are useful in the hydrodesulfurization and denitrogenation of hydrocarbon feed stocks and the saturation of aromatics contained therein.

Abstract: Lubricants are stabilized against wear and corrosion by adding an additive amount of a novel substituted thiadiazole. These are derived from 2,5-dimercapto-1,3,4-thiadiazole and other moieties, as for example an organophosphorus moiety.

Abstract: Lubricant compositions comprising an oil of lubricating viscosity and a minor proportion of water containing in an amount sufficient to counteract the accelerating effect of water on metal fatigue an amine salt of a half-ester of a substituted succinic acid. Greases containing the above-described amine salts are also provided.

Abstract: The antiwear and load carrying properties of lubricants are improved by incorporating therein a product prepared by reacting a chlorinated wax with a trihydrocarbyl phosphite.

Abstract: Alkenylsuccinic anhydride is reacted with an amino alcohol, such as tris(hydroxymethyl)aminomethane, to provide intermediate reaction products from which novel derivatives are obtained by reacting the said intermediate product with boric acid or organoborates, organophosphonates and aldehydes. The intermediate reaction product prepared from tris(hydroxymethyl)aminomethane contains unexpectedly an oxazoline component when the reaction is carried out at 175.degree. C or below, preferably 100.degree. to 175.degree. C. The reaction products and their derivatives are particularly useful in lubricants, fuels or other industrial fluids as detergents.

Abstract: Aluminosilicate zeolites are prepared containing an outer aluminum-free shell. The outer shell is essentially SiO.sub.2 that has crystallized on the zeolite surface in the ZSM-5 type configuration, leading to a more selective catalyst.

Abstract: Using a novel process of one or more combined steps, modified novel block copolymers are prepared by alkylating or hydrogenating a block copolymer precursor containing at least two segments, in which segment A consists of a styrene polymer, either styrene alone or a hydrogenated random butadiene-styrene copolymer and from 1% to about 50% by weight of segment B being an alkylene oxide or sulfide copolymerized with the first segment as an AB or BAB copolymer. These novel copolymers perform as multifunctional additives in industrial organic compositions, both hydrocarbon fluids, such as petroleum-derived, and non-hydrocarbon, or synthetic fluids, providing such utility as detergency, emulsification and viscosity index improvement. These copolymers have molecular weights in the range of from about 1,000 to 500,000. The copolymers are particularly useful in lubricating oils, greases and fuels, especially cross-graded lubricants, crude oils, diesel oils, gasoline and fuel oils.

Abstract: The detergency properties of a fuel or a lubricant are improved by adding thereto a Mannich base product prepared by reacting a high molecular weight alkyl substituted hydroxyaromatic compound, a polyoxyethylene polyamine and an aldehyde.

Abstract: This invention is directed to the shape selective conversion of a hydrocarbon charge over erionite which has been activated by the steps comprising calcining the erionite as a first step, contacting with a solution of an ammonium salt, contacting with a solution of metal salt containing a metal such as calcium, calcining again, contacting again with a solution of an ammonium salt and then with a solution of a metal salt containing nickel or another similar metal, and finally calcining. It is also directed to the catalyst utilized in affecting said conversion and to the method for preparing such catalyst.

Abstract: The invention is an improvement in the process of benificiating phosphate ores, the process including at least one acid flotation and at least one amine flotation. The improvement is a reduction in the formation of slimes, obtained by drying the phosphate ore prior to classification and flotation or by transporting it to the flotation plant out of contact with water.
