The catalytic reduction of CO 2 accompanying the aromatization of propane is a new type of catalytic reaction for the utilization of CO 2 . CO 2 is reduced into CO by hydrocarbon, and hydrocarbon (propane) is converted into more valuable products. This type of reaction is more economical than the hydrogenation of CO 2 , since propane is much cheaper than hydrogen. The combined conversion of propane and CO 2 was investigated by using metal‐loaded ZSM‐5 catalysts, which were characterized by temperature‐programmed desorption, X‐ray diffraction, thermogravimetric analysis and BET analysis. Reduction of CO 2 by propane resulted in higher conversion of CO 2 and higher CO yield than that by hydrogen. The incorporation of metal ions, such as Zn 2+ , Cr 3+ , Fe 3+ and Ni 2+ , into HZSM‐5 enhanced the catalytic activity for CO 2 reduction. The addition of CO 2 was found to suppress the coke deposition during the aromatization of propane. Copyright © 2000 John Wiley & Sons, Ltd.
