A study of CO2 utilization in the production of sustainable fuel has identified tandem-type hydrocarbon synthesis from methanol as a notable process. Tandem-type catalysts, comprising metal oxides and zeolites, was chosen as effective catalysts for this reaction. In this study, our focus was placed on ZnFe2O4 spinel, which showed activity at 653 K, a temperature that is suitable for the conversion of methanol to hydrocarbons. The catalysts with the addition of Al and Ga were prepared and mixed with SSZ-13 zeolite to observe the hydrocarbon production behavior. Specifically, the quantity of spinel added to the zeolite was varied to compare hydrocarbon yields, and the catalytic properties of ZnFe2O4-based spinels were studied.
