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.
