The composition comprises branched C.sub.30 -C.sub.10000 hydrocarbons that have a branch ratio of less than 0.19 and viscosity at 100.degree. C. between 725 cS and 15,000 cS. The novel compositions comprise the product of the oligomerization of C.sub.6 to C.sub.20 alpha-olefin feedstock, or mixtures thereof, under oligomerization conditions at a temperature between -20.degree. C. and +90.degree. C. in contact with a reduced valence state Group VIB metal catalyst on porous support. The compositions have viscosities at 100.degree. C. between 725 cS and 15,000 cS.

    摘要: A process for producing oligomers from alpha-olefins, such as 1-decene, in which the olefins are oligomerized over a supported, reduced metal oxide catalyst from Group VIB of the Periodic Table to give oligomers with a branch ratio of less than 0.19. The catalyst, preferably a chromium/silica catalyst the catalyst can be regenerated to allow repeated recycling of the catalyst without a loss in yield of the oligomer product. The regeneration process comprises: (i) purging or stripping the deactivated catalyst with inert gas at elevated temperature to strip unreacted olefin and oligomer product from the catalyst; (ii) contacting the deactivated and purged catalyst with a stream of oxidizing gas while heating to elevated temperature to oxidize the metal component of the catalyst and remove carbonaceous deposits from the catalyst; (iii) cooling the oxidized catalyst and contacting it with a stream of reducing gas to reduce the metal component of the oxidized catalyst to a lower valence state. The oligomerization may be carried out at relatively high temperatures of about 90.degree. to 250.degree. C. to produce liquid lubricant products of high viscosity index, typically above 130, or at lower temperatures from about -20.degree. to about +90.degree. C. to product products of higher molecular weight which may be used as lubricant additives, e.g. VI improvers. The high molecular weight products are generally characterized by a branch ratio less than 0.19, a weight average molecular weight from about 15,000 to 200,000, a number average molecular weight from about 5,000 to about 50,000 and a molecular weight distribution from about 1 to about 5. They are also shear stable under high temperature, high shear rate conditions of 150.degree. C. and a shear rate of 10.sup.6 second.sup.-1.

    摘要: A process for producing liquid oligomers useful as lubricants from alpha-olefins feedstock, such as 1-decene. The olefins are oligomerized over a supported and reduced metal oxide catalyst from Group VIB of the Periodic Table to produce the oligomers. The chromium-on-silica oligomerization catalysts can be regenerated to allow repeated recycling of the catalyst with reduced losses in yield of the lubricant. The regeneration process is particularly useful to regenerate catalyst deactivated during the course of oligomerization at high temperatures to produce low viscosity HVI-PAO lubricant. The regeneration process is carried out by (i) purging the deactivated catalyst with inert gas to strip unreacted olefin and lubricant product; (ii) contacting the purged catalyst with a stream of oxidizing gas at an elevated temperature to oxidize the carbonaceous deposits; and (iii) cooling the catalyst and contacting it with a stream of reducing gas to reduce the metal component to a lower valence state.

    摘要: A process for oligomerizing alpha olefins to produce hydrocarbon oligomers useful as lubricants and lubricant additives uses a catalyst comprising a supported reduced group VIB metal, preferably chromium, in the form of its oxide. The support is a mesoporous, inorganic, crystalline solid of unique structure, of novel pore geometry. The preferred forms of these mesoporous materials are characterized by substantially uniform hexagonal honeycomb microstructure, with uniform pores having a cell diameter greater than 13 .ANG., preferably in the mesoporous range of about 20-100 .ANG.. The use of the catalysts made with the mesoporous support materials enables products of greater viscosity to be made as compared to the products from catalysts using amorphous supports. The catalyst is usually used under oligomerization conditions at a temperature of about 90.degree. to 250.degree. C. to produce liquid hydrocarbon oligomers in the lubricant range which have a branch ratio of less than 0.19 and high values of viscosity index.

    摘要: A process is disclosed for the production of novel monoalkylbenzenes or substituted benzenes by aromatics alkylation wherein the alkylation catalyst is an acidic shape selective metallosilicate catalyst and the alkylating agent is the olefins dimer by-product of the oligomerization of alpha-olefins in contact with reduced valence state solid chromium oxide catalyst on a porous support. The alkylated benzenes produced comprise those mono-alkylbenzenes wherein the alkyl group contains 12 to 28 carbon atoms and have high viscosity index, low pour point and low viscosity. They have a low degree of residual olefinic unsaturation and are useful as additives to thermally and oxidatively stabilize lubricant materials. The process comprises reacting benzene or substituted benzene with C.sub.6 -C.sub.14 alpha-olefin olefinic dimer having a branch ratio of less than 0.19, or mixture of said dimers, in contact with acidic shape selective zeolite catalyst having large pore size.
