  • Publication number: 20220008908
    Abstract: A method for producing a hydrocracking catalyst includes preparing a framework substituted Y-type zeolite, preparing a binder, co-mulling the framework substituted Y-type zeolite, the binder, and one or more hydrogenative metal components to form a catalyst precursor, and calcining the catalyst precursor to generate the hydrocracking catalyst. The framework substituted Y-type zeolite is prepared by calcining a Y-type zeolite at 500° C. to 700° C. to form a calcined Y-type zeolite. Further, the framework substituted Y-type zeolite is prepared by forming a suspension containing the calcined Y-type zeolite, the suspension having a liquid to solid mass ratio of 5 to 15, adding acid to adjust the pH of the suspension to less than 2.0, adding and mixing one or more of a zirconium compound, a hafnium compound, or a titanium compound to the suspension, and neutralizing the pH of the suspension to obtain the framework substituted Y-type zeolite.

  • Patent number: 11180432
    Abstract: Relatively low value disulfide oil (DSO) compounds produced as by-products of the mercaptan oxidation (MEROX) processing of refinery hydrocarbon streams, and oxidized disulfide oils (ODSO), are economically converted to value-added BTX by introducing the DSO and/or ODSO compounds as the feed to a fluidized catalytic cracking (FCC) unit and recovering the liquid products. The liquid FCC products are introduced as the feedstream to a selective naphtha hydrogenation and hydrotreating process for desulfurization and are then further separated in an aromatics extraction process for the recovery of BTX.

  • Patent number: 11180701
    Abstract: Hydrocracked bottoms fractions are treated to separate HPNA compounds and/or HPNA precursor compounds and produce a reduced-HPNA hydrocracked bottoms fraction effective for recycle, in a configuration of a single-stage hydrocracking reactor, series-flow once through hydrocracking operation, or two-stage hydrocracking operation. A process for separation of HPNA and/or HPNA precursor compounds from a hydrocracked bottoms fraction of a hydroprocessing reaction effluent comprises contacting the hydrocracked bottoms fraction with an effective quantity of a non-polar solvent to promote precipitation of HPNA compounds and/or HPNA precursor compounds. The soluble hydrocarbons in the hydrocracked bottoms fraction are separated into an HPNA-reduced hydrocracked bottoms portion that is recycled within hydrocracking operations.

  • Patent number: 11168269
    Abstract: An integrated refinery process for producing diesel fuel blending stock from olefinic heavy naphtha streams that contain gasoline and compounds with carbon numbers in the range of from 9-14 are oxidized and converted into their corresponding oxides in the presence of a homogeneous or heterogeneous catalyst, or both, and optionally an acid phase transfer agent for the liquid reactants, the product oxides having boiling points about 34° C. higher than the corresponding olefins, and as a result, in the diesel blending component boiling point range. The oxygenates produced have lubricating properties that enhance the typically poor lubricity characteristics of ultra-low sulfur diesels and reduce the need for additives to improve the lubricity of the blended diesel fuels.
