摘要： According to embodiments, a process of forming a catalyst for aromatizing hydrocarbons may include enhancing a mesoporosity of a zeolite support by a base-leaching treatment, an acid-leaching treatment, or both to form a zeolite support having enhanced mesoporosity, mixing the zeolite support having enhanced mesoporosity with a solution containing zinc or gallium to disperse the zinc or gallium on the zeolite support having enhanced mesoporosity, and calcining the zeolite support having enhanced mesoporosity with zinc or gallium dispersed thereon to form a zinc- or gallium-doped zeolite catalyst having a mesopore volume of greater than 0.09 cm3/g and less than 0.20 cm3/g.

摘要： Methods that increase production of a liquid transportation fuel blend component by utilizing C5 hydrocarbon streams taken from both a refinery naphtha stream and an NGL fractionator pentanes plus stream. A high vapor pressure pentane fraction from the NGL fractionator is separated to remove isopentane and produce lower vapor pressure commodity natural gasoline. A refinery naphtha stream (that is optionally an FCC naphtha stream) is separated to produce a C5 olefins stream that is then oligomerized to produce an upgraded stream having lower vapor pressure and higher octane rating, then combined with the remainder of the naphtha stream as well as the isopentane stream to produce a gasoline blend component that meets specifications for vapor pressure and octane rating.

摘要： According to embodiments, a process for aromatizing hydrocarbons may include contacting the hydrocarbons with a zinc- or gallium-doped ZSM-5 catalyst having a mesopore volume of greater than 0.09 cm3/g. Contacting the hydrocarbons with the catalyst causes a least a portion of the hydrocarbons to undergo chemical reactions to form aromatic hydrocarbons.

摘要： A method of producing a hierarchical zeolite composite catalyst. The method including dissolving, in an alkaline solution and in the presence of a surfactant, a catalyst precursor comprising mesoporous zeolite to yield a dissolved zeolite solution, where the mesoporous zeolite comprises large pore mordenite and medium pore ZSM-5. The method also including condensing the dissolved zeolite solution to yield a solid zeolite composite from the dissolved zeolite solution and heating the solid zeolite composite to remove the surfactant. The method further including impregnating the solid zeolite composite with one or more active metals selected from the group consisting of molybdenum, platinum, rhenium, nickel, and combinations thereof to yield impregnated solid zeolite composite and calcining the impregnated solid zeolite composite to produce the hierarchical zeolite composite catalyst. The hierarchical zeolite composite catalyst has a mesostructure comprising at least one disordered mesophase and at least one ordered mesophase.

摘要： The present invention provides a steam reforming process for heavy oil or hydrocarbons using a circulating fluidized bed reactor, the process having a reforming step and a regeneration step, wherein the reforming step and the regeneration step comprise a fluidized reactor containing a fluidizable nickel-containing reforming catalyst and produce hydrogen as a product of the reforming bed. The invention produces high purity hydrogen in the synthesis gas product stream and avoids irreversible fouling on the catalyst.

摘要： A cascade reactor scheme with acid and hydrocarbon flowing in reverse directions. The systems and processes for alkylation of olefins herein may include providing a first olefin to a first alkylation zone, and a second olefin to a second alkylation zone. Isoparaffin may be provided to the first alkylation zone. The isoparaffin and first olefin may be contacted with a partially spent sulfuric acid in the first alkylation zone to form a spent acid phase and a first hydrocarbon phase including alkylate and unreacted isoparaffin. The first hydrocarbon phase and second olefin may be contacted with a sulfuric acid feed in the second alkylation zone to form a second hydrocarbon phase, also including alkylate and unreacted isoparaffin, and the partially spent sulfuric acid that is fed to the first alkylation zone. Further, the second hydrocarbon phase may be separated, recovering an isoparaffin fraction and an alkylate product fraction.
