摘要： There is provided a method and catalyst for removing catalyst-poisoning impurities or contaminants such as arsenic, iron and nickel from hydrocarbonaceous fluids, particularly shale oil and fractions thereof. More particularly there is provided a method of removal of such impurities by contacting the fluids with a copper-Group VIA metal-alumina catalyst. For example, a copper-molybdenum-alumina catalyst may be used as a guard bed material in a step preceding most refining operations, such as desulfurization, denitrogenation, catalytic hydrogenation, etc.

摘要： Long chain alkyl substituted naphthalenes are produced by alkylating naphthalene with an olefin or other alkylating agent with at least 6, and usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite having rare earth cations, and both ammonium and protonic species, associated with the exchangeable sites of the zeolite. The zeolite is usually a large pore size zeolite such as USY. The presence of rare earths and both ammonium and protonic species increases selectivity for production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.

摘要： Olefins are converted to lower alkene hydrocarbon products, e.g., propene, butenes, and isoalkenes with zeolite MCM-22 catalyst. This catalytic conversion is particularly useful in the selective separation of linear olefins in mixed hydrocarbon streams, employing MCM-22 catalyst to convert these straight-chain unsaturated components to lighter products, particularly, C.sub.3 -C.sub.4 olefins. One potential application of this selective separation is in the removal of linear olefins from FCC gasoline.

摘要： Long chain alkyl substituted aromatic compounds, particularly alkylated naphthalenes are produced by the alkylation of aromatics, e.g. naphthalene, with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst which comprises a mesoporous crytalline material. The mesoporous material has pores with diameters of at least 13 .ANG. which, in the preferred catalytic form, are arranged in a uniform hexagonal arrangement, and have a X-ray diffraction pattern with at least one d-spacing greater than about 18 .ANG.. These materials exhibit benzene adsorption capacities greater than about 15 grams benzene per 100 grams at 50 torr and 25.degree. C. In its preferred catalytic form, the crystalline material exhibits a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 .ANG. which corresponds to at least one peak in the X-ray diffraction pattern.

摘要： The thermal and oxidative stability of HVI-PAO olefin oligomers is improved by alkylation in the presence of a solid, porous, acidic alkylation catalyst defined by a specific X-ray diffraction pattern. A preferred catalyst is the synthetic zeolite MCM-22. The olefinic oligomers used as alkylating agents are prepared from 1-alkene oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica. Aromatics which may be used in the reaction include monocyclic aromatics such as benzene and toluene as well as bicyclic aromatics such as naphthalene. Substituted aromatics may be used in order to introduce functional groups such as hydroxyl groups into the products, for example by the use of hydroxyaromtics such as phenol or naphthaol. The alkylated aromatic hydrocarbon products retain the unique features of the alkylating olefinic oligomer and exhibit high viscosity index and low pour point as well as improved thermal and oxidative stability and additive solvency characteristics.

摘要： A hydrocarbonaceous feedstock upgrading process is disclosed. Spent nickel arsenide-containing catalyst from demetallation guard chambers or hydroprocessing operations are utilized to upgrade the hydrocarbonaceous feedstock prior to dearsenation. The spent catalysts have significant activity for diolefin saturation and CCR removal at temperatures low enough to reduce olefin polymerization reactions.
