  • Publication number: 20200239382
    Abstract: A process for acid catalyzed alkylation involving the use of surfactants which form bi-continuous micro-emulsions with the liquid acid and the hydrocarbon is described. The bicontinuous phase formed between the hydrocarbon and liquid acid phases at surfactant addition facilitates and improves the liquid acid catalyzed alkylation reactions including motor-fuel alkylation reaction.

  • Patent number: 10703990
    Abstract: A process is disclosed for using an iron oxide and alumina catalyst with no more than more than about 55 wt % of the alumina in the diaspore phase or in the alpha phase in SHC. Alpha alumina is less effective catalyst component for slurry hydrocracking in terms of TIOR conversion. Drying procedures should avoid more than about 51 wt % of the alumina change to the alpha phase. The SHC catalyst is for converting heavy hydrocarbon feed into lighter hydrocarbon products.

  • Patent number: 10703700
    Abstract: A liquid phase selective oxidation process is described. The process involves the partial oxidation of alkanes to partially oxidized products. A lower alkane, a solvent, and a soluble metal catalyst are contacted in the presence of an oxidizing agent in a reaction zone under partial oxidation conditions to produce the partially oxidized products. The partially oxidized products include one or more of lower alkyl alcohols, lower alkyl ketones, and lower alkyl acetates. The soluble metal catalyst is a soluble metal salt of cobalt, manganese, chromium, titanium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, zirconium, or combinations thereof, and the promoter comprises a bromine source, an imide source, or combinations thereof.

  • Patent number: 10369556
    Abstract: An integrated process for gasoline production is described. The process includes introducing a feed comprising n-C5 hydrocarbons into a disproportionation reaction zone in the presence of a disproportionation catalyst to form a disproportionation mixture comprising iso-C4 and C6+ disproportionation products and unreacted n-C5 hydrocarbons. An iso-C4 hydrocarbon stream and an olefin feed are introduced into an alkylation reaction zone in the presence of an alkylation catalyst to produce an alkylation mixture comprising alkylate and unreacted iso-C4 paraffins. The disproportionation mixture and the alkylation mixture are combined, and the combined mixture is separated into at least a stream comprising the alkylate product, an iso-C4 stream, and an unreacted n-C5 hydrocarbon stream. The iso-C4 stream is recycled to the alkylation reaction zone, and the unreacted n-C5 hydrocarbon stream is recycled to the disproportionation reaction zone. The stream comprising the alkylate product is recovered.

  • Patent number: 10195588
    Abstract: A process and catalyst is disclosed for converting a heavy hydrocarbon feed stream into lighter hydrocarbon products using a two component catalyst. The catalyst comprises iron and molybdenum containing catalyst. Alumina may be a third catalyst component. The molybdenum is present in the heavy hydrocarbon feed stream at about 500 wppm or less and the weight ratio of iron to the molybdenum is less than 5. Much lower concentrations of expensive molybdenum can be used due to the addition of iron in the catalyst.
