  • 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.

  • 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.

  • 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.

  • Patent number: 9732284
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The slurry hydrocracking reaction can be controlled by measuring the production of mesophase using X-ray diffraction. Upon a mesophase yield fraction reaching a predetermined level, reaction conditions should be moderated to avoid excessive coke production.
