摘要： The present invention features a direct synthesis of light olefins through the hydrogenation of carbon dioxide. In2O3 supported on cubic phase yttria-stabilized zirconia is used as a catalyst and is mixed with a molecular sieve to perform the hydrogenation. The cubic crystal structure of the yttria-stabilized zirconium dioxide is an excellent support for indium oxide particles and prevents their deactivation during CO2 hydrogenation. This direct synthesis route promotes a stable and efficient method for producing light olefins.

摘要： 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.
