  • Processes of forming metal-doped zeolite catalysts with enhanced mesoporosity
    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.

  • Aromatization of light hydrocarbons using metal-modified zeolite catalysts
    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.

  • Aromatization of light hydrocarbons using metal-doped zeolite catalysts with enhanced mesoporosity
    Patent number: 11465950
    Abstract: 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.
