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.

The present invention relates to a supported catalyst system for olefin polymerization which comprises at least one metallocene component and a support of an inorganic oxide of silica, aluminum or a polymer containing hydroxyl groups. The support is modified with an organogermane and/or organotin compound. The inventive catalyst system produces minimal reactor fouling, has excellent productivity and good hydrogen responsiveness. The present invention also relates to a process for preparing the catalyst system and to the slurry/suspension or gas-phase polymerization of olefins using the catalytic system, optionally with a small amount of aluminoxane cocatalyst.
