Abstract: A process for catalytically directly producing hydrogen peroxide (H2O2) product from hydrogen and oxygen-containing feeds by contacting them with a supported noble metal phase-controlled catalyst and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14×10−4 and 5.0×10−4 at reaction condition of 0-100° C. temperature and 100-3,000 psig pressure. Unconverted feed gas and organic liquid solvent solution are usually recovered and recycled back to the reactor along with any recovered catalyst. If desired, the hydrogen peroxide product can be fed together with an organic chemical feedstock such as propylene and with the organic liquid solvent solution into a second catalytic reaction step which oxidizes the feedstock to produce a desired crude oxidized organic product such as propylene oxide, which may be purified by distillation steps and recovered from the solvent solution.

Abstract: The thermal and oxidative stability of HVI-PAO olefin oligomers is improved by reaction of the oligomerization mixture containing the olefin oligomer, dimer and isomerized but unoligomerized olefin with an aromatic compound such as toluene, xylene or naphthalene. The reaction is carried out in the presence of an acidic catalyst, which may be heterogeneous solid catalyst such as an acidic clay or a crystalline zeolite such as MCM-22, a homogeneous Friedel-Crafts catalyst such as AlCl.sub.3, BF.sub.3 or their complexes or a supported catalyst such as AlCl.sub.3 on graphite or silica. The reaction improves the yield and thermal stability of the lube range products. The olefinic oligomer mixture which is reacted with the aromatic compound is prepared from 1-alkene oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica.

Abstract: The stability of HVI-PAO olefin oligomers is improved by reaction of the oligomer over an acidic function catalyst which introduces aromatic groups into the oligomer by cracking a portion of the oligomer to form cracking fragments which are then aromatized to aromatics which are subsequently alkylated by the oligomer. This reaction incorporates an aromatic function into the oligomer to produce a modified oligomer product of improved stability. The olefinic oligomers are prepared from 1-alkene by oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica. The products retain the unique features of the olefin oligomer and exhibit high viscosity index and low pour point as well as improved thermal and oxidative stability and additive solvency characteristics resulting from the introduction of aromatic moieties into the structure of the oligomer by the intramolecular dehydrocyclization reaction.

Abstract: The disclosure reveals that aromatic structures can be introduced into the molecular structure of polyalpha-olefin lubricant oligomers by subjecting the polyalpha-olefin to a dehydrocyclization reaction which converts a portion of the pendant or branching alkyl groups in the recurring polymeric unit of PAO to aromatic structures. When the starting material for dehydrocyclization is PAO prepared by oligomerization of C.sub.6 -C.sub.20 alpha-olefins in contact with reduced chromium oxide catalyst on porous support the dehydrocyclization reaction produces a lubricant oligomer with increased aromaticity without significantly degrading the viscometric properties of the feedstock lubricant, particularly the high VI of the starting material. The aromatic structures introduced lend increased thermal stability, wear resistance and solubilizing characteristics to the liquid lubricant oligomers so modified.

Abstract: 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.

Abstract: 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 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.
