  • 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.

  • Publication number: 20190062647
    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.

  • Publication number: 20190062247
    Abstract: A liquid phase selective oxidation process is described. The process involves the partial oxidation of alkanes to 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: 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.

  • Publication number: 20180273463
    Abstract: Impure aromatic carboxylic acids such as are obtained by liquid phase oxidation of feed materials comprising aromatic compounds with substituent groups oxidizable to carboxylic acid groups, or comprising aromatic carboxylic acid and one or more aromatic carbonyl impurities that form hydrogenated species more soluble in aqueous solvents or with less color or color-forming tendencies than the aromatic carbonyl impurity, are purified to an aromatic carboxylic acid product with lower levels of impurities by a process comprising contacting an aqueous solution comprising the impure aromatic carboxylic acid with hydrogen at elevated temperature and pressure with an attrition-resistance, acid stable catalyst composition comprising at least one hydrogenation catalyst metal and a support comprising relatively high surface area of high porosity silicon carbide with low levels of iron and alkali metal impurities. The support may further contain titanium or rare earth metals.

  • Patent number: 10047021
    Abstract: A process of tuning a hydrocarbon product composition is described. The process involves selecting paraffins for reaction. The equilibrium constants for reactions of the selected paraffins can be used to select appropriate feed ratios, or an equilibrium composition as function of C/H molar ratio. A selected feed is reacted to obtain the product. Equilibrium product compositions and non-equilibrium product compositions can be obtained using the process.

  • Patent number: 9914675
    Abstract: Alkylation processes are described. The processes utilize ionic liquid catalysts having a kinematic viscosity range of about 50 cSt to about 100 cSt at 25° C. Catalysts within this range produce alkylate having higher octane than catalysts outside this range, especially at higher process temperatures which are preferable from an operating cost standpoint. The alkylate can have one or more of a research octane number of at least about 93, a selectivity of C8 of at least about 65%, and a mole ratio of trimethylpentane to dimethylhexane of greater than about 7:1.
