  • Patent number: 11866389
    Abstract: 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.

  • Patent number: 11760943
    Abstract: A process for upgrading a hydrocarbon feed includes contacting the hydrocarbon feed with steam in the presence of a cracking catalyst in a steam catalytic cracking reactor at reaction conditions sufficient to cause at least a portion of hydrocarbons in the hydrocarbon feed to undergo one or more cracking reactions to produce a steam catalytic cracking effluent comprising light olefins, light aromatic compounds, or both, where the cracking catalyst comprises a ZSM-11 zeolite.

  • Patent number: 11725149
    Abstract: A fluid catalytic cracking catalyst composition (FCC catalyst composition) includes an FCC catalyst and from 1 wt.% to 30 wt.% aromatization-promoting FCC additive. The FCC catalyst includes a USY zeolite, and the aromatization-promoting FCC additive is an MFI zeolite modified with an aromatization compound. The aromatization compound is a metal or metal oxide that includes a metal element from periods 4-6 of the IUPAC periodic table. A method for upgrading a hydrocarbon feed includes contacting the hydrocarbon feed with the FCC catalyst composition at reaction conditions sufficient to upgrade at least a portion of the hydrocarbon feed.

  • Patent number: 11673845
    Abstract: Embodiments of the present disclosure are directed to processes for aromatizing hydrocarbons includes contacting the hydrocarbons with a catalyst including at least two different metal modifiers dispersed on surfaces of a hydrogen-form medium-pore zeolite support. Each of the at least two different metal modifiers comprises a metal selected from the group consisting of IUPAC Groups 3-12, and lanthanide metals, and the catalyst is substantially free of gallium. Contacting the hydrocarbons with the catalyst causes a least a portion of the hydrocarbons to undergo a chemical reaction to form aromatic hydrocarbons.
