Patent number: 11472755Abstract: Method of making BTX compounds including benzene, toluene, and xylene, including feeding heavy reformate to a reactor containing a composite zeolite catalyst. The composite zeolite catalyst includes a mixture of layered mordenite (MOR-L) comprising a layered or rod-type morphology with a layer thickness less than 30 nm and ZSM-5. The MOR-L, the ZSM-5, or both include one or more impregnated metals. The method further includes producing the BTX compounds by simultaneously performing transalkylation and dealkylation of the heavy reformate in the reactor. The composite zeolite catalyst is able to simultaneously catalyze both the transalkylation and dealkylation reactions.Type: GrantFiled: July 13, 2021Date of Patent: October 18, 2022Assignees: SAUDI ARABIAN OIL COMPANY, CONSEJO SUPERIOR DE INVESTIGACIONES CIENTIFICAS, UNIVERSITAT POLITECNICA DE VALENCIAInventors: Raed Hasan Abudawoud, Avelino Corma Canos, M.

Patent number: 11097262Abstract: 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.Type: GrantFiled: April 20, 2018Date of Patent: August 24, 2021Assignee: Saudi Arabian Oil CompanyInventors: Veera Venkata Ramakrishna Tammana, Raed Hasan Abudawoud, Ahmad A.
