  • Patent number: 11097262
    Abstract: 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.
