  • Patent number: 4206040
    Abstract: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a novel attenuated superactive multimetallic catalytic composite comprising a combination of a catalytically effective amount of a pyrolyzed rhenium carbonyl component with a porous carrier material containing a uniform dispersion of a catalytically effective amount of a platinum group component, which is maintained in the elemental metallic state, and of a silver component. In a highly preferred embodiment, this novel catalytic composite also contains a catalytically effective amount of a halogen component. A specific example of the type of hydrocarbon conversion process disclosed herein is a process for the catalytic reforming of a low octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with this attenuated superactive multimetallic catalytic composite at reforming conditions.

  • Patent number: 4203826
    Abstract: High-purity C.sub.7 and/or C.sub.8 aromatic hydrocarbons are produced by reforming a C.sub.7 or C.sub.8 full boiling carbon number naphtha feed fraction or combinations thereof under reforming conditions of sufficient severity to convert essentially all of the non-aromatic portion of the naphtha feed boiling in the C.sub.7 to C.sub.8 aromatic boiling range to C.sub.7 and/or C.sub.8 aromatics, and then separating the reformate by fractional distillation into high-purity fractions of C.sub.7 and/or C.sub.8 aromatic hydrocarbons. Preferably, the C.sub.7 and/or C.sub.8 full boiling carbon number naphtha feed fraction is reformed in a plurality of reformer reaction stages with increasingly more severe conditions in order to maximize the yield of the C.sub.7 and C.sub.8 aromatics.

  • Patent number: 4197419
    Abstract: Tantalum catalysts or catalyst precursors of the formula ##STR1## wherein X is a halide, or alkoxide and L is an alkene (CH.sub.2 .dbd.CHR) having from 2 to 20 carbon atoms, react with 1-olefins to give catalysts of the formula ##STR2## wherein R.sup.2 is hydrogen or a C.sub.1 to C.sub.18 alkyl such as methyl, ethyl, or propyl. The catalysts or catalyst precursors selectively dimerize 1-olefins to the two possible disubstituted .alpha.-olefin dimers, the ratio of which depends on the nature of R.

  • Patent number: 4197187
    Abstract: Hydrocarbon hydroconversion, especially hydrocarbon reforming, using catalysts whose supports have been prepared by a sol-gel process. For hydrocarbon reforming, it is preferred that the primary particles used to prepare the porous gel should have been prepared by a vapor phase condensation method, for example flame hydrolysis and that the support should have a narrow pore size distribution. The process produces much less gas by hydrocracking at given aromatics yields than comparative processes using conventional catalysts.

  • Patent number: 4197421
    Abstract: This invention relates to the use of a three compartment electrolytic cell in the production of synthetic carbonaceous fuels and chemical feedstocks such as gasoline, methane and methanol by electrolyzing an aqueous sodium carbonate/bicarbonate solution, obtained from scrubbing atmospheric carbon dioxide with an aqueous sodium hydroxide solution, whereby the hydrogen generated at the cathode and the carbon dioxide liberated in the center compartment are combined thermocatalytically into methanol and gasoline blends. The oxygen generated at the anode is preferably vented into the atmosphere, and the regenerated sodium hydroxide produced at the cathode is reused for scrubbing the CO.sub.2 from the atmosphere.

  • Patent number: 4191638
    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.
