  • Patent number: 10260012
    Abstract: In a process for reducing the level of benzene in a refinery gasoline feed containing benzene and at least one C4+ olefin, the feed is contacted with a first alkylation catalyst under conditions effective to react at least part of the C4+ olefin and benzene in the refinery gasoline feed and produce a first effluent containing C10+ hydrocarbons. At least part of the C10+ hydrocarbons is removed from the first effluent to produce a second effluent, which is then contacted with an alkylating agent selected from one or more C2 to C5 olefins in the presence of a second alkylation catalyst to produce a third effluent which has reduced benzene content as compared with the second effluent.

  • Publication number: 20140142204
    Abstract: A process and system are described for producing a synthetic crude oil by contacting a synthesis gas with a combination of a synthesis gas conversion catalyst and a hydroconversion catalyst in a synthesis gas reactor. The synthesis gas can be obtained from gas associated with crude oil production, i.e., associated gas, in a synthesis gas generator. The synthetic crude oil can be blended with a natural crude oil to produce a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil. The resulting blended stabilized crude oil has improved flow characteristics including a pour point of 30° C. or less.

  • Patent number: 8721871
    Abstract: A process for the hydroprocessing of a low value light cycle oil (LCO) hydrocarbon feed to provide a high-value diesel-range product. The process comprises a hydrotreatment stage followed by a hydrocracking stage, each of which is conducted under liquid-full reaction conditions wherein substantially all the hydrogen supplied to the hydrotreating and hydrocracking reactions is dissolved in the liquid-phase hydrocarbon feed. Ammonia and other gases formed during hydrotreatment are removed in a separation step prior to hydrocracking. The LCO feed is advantageously converted to diesel in high yield with little loss of hydrocarbon to naphtha.

  • Publication number: 20140114097
    Abstract: A method and apparatus is provided for the continuous microwave depolymerization of high molecular weight organic feedstock material, such as waste plastics and includes intermittent or continuous feeding of the processing material on the surface or into the bulk of the sensitized hot bed located under microwave irradiation. As a result of the interaction of electromagnetic field with processed materials, sensitizer is heated by microwave energy and feedstock material undergoes the depolymerization reactions. The reaction zone can be localized on the surface of the hot bed or distributed in the bulk of the reaction mass depending on the agitation conditions of the reaction mass, such as stirring, or other agitation means, for example by re-circulated gas. Products of the reactions are vaporized and transported to the collection system, which may include a combination of a scrubber, a condenser and a settler.

  • Patent number: 8691080
    Abstract: One exemplary embodiment can include a slurry hydrocracking process. The process can include combining one or more hydrocarbons and a slurry hydrocracking catalyst as a feed to a slurry hydrocracking reaction zone, fractionating an effluent from the slurry hydrocracking reaction zone, separating the pitch from at least a portion of the slurry hydrocracking catalyst, and recycling the suspension to the slurry hydrocracking reaction zone. The slurry hydrocracking catalyst may include a support. Fractionating the effluent may provide a light vacuum gas oil, a heavy vacuum gas oil, and a mixture comprising a pitch and the slurry hydrocracking catalyst. Generally, the separated slurry hydrocracking catalyst is comprised in a suspension.

  • Patent number: 8440071
    Abstract: A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a catalyst precursor capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by 1) premixing the catalyst precursor with a hydrocarbon diluents to form a catalyst precursor mixture, 2) mixing the catalyst precursor mixture with the heavy oil feedstock, and 3) raising the temperature of the feedstock to above the decomposition temperature of the catalyst precursor to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment.
