Processes for aromatizing hydrocarbons include contacting the hydrocarbons with a catalyst composition comprising a metal oxide dispersed on a surface of a zeolite support, where contacting the hydrocarbons with the catalyst composition causes at least a portion of the hydrocarbons to undergo a chemical reaction to form aromatic hydrocarbons. The catalyst composition is prepared by a synthesis process that includes combining the zeolite support with a hydrocarbon solvent to form a zeolite mixture, where the hydrocarbon solvent pre-wets the pores of the zeolite support. The synthesis process further includes combining a polar solvent comprising a metal salt with the zeolite mixture to form an impregnated zeolite support. The synthesis process also includes drying the impregnated zeolite support and calcining the impregnated zeolite support to convert the metal salt to the metal oxide, thereby forming the catalyst composition.

Catalyst compositions for aromatizing hydrocarbons and processes for producing aromatic compounds using the catalyst compositions

A method for producing a fluoride functionalized zeolite catalyst is described, having a F/Si molar ratio of 0.1:1-3:1. The method involves mixing a fluoride salt with zeolite components to form a gel, which is then hydrothermally treated and calcined. The fluoride functionalized zeolite catalyst may be used for cracking an olefin stream into ethylene, propylene, and butylene, with high selectivity towards propylene. The fluoride functionalized zeolite catalyst may be used for 50 or more hours with a stable conversion rate and low coke formation.
