Change of catalytic properties of Fesingle bondZnO/zeolite composite catalyst in the hydrogenation of carbon dioxide Original Research Article

The hydrogenation of carbon dioxide was examined using the composite catalysts which were obtained by the physical mixing of Fesingle bondZnO and HY zeolite. Fesingle bondZnO was a typical F-T (Fischer-Tropsch) catalyst and Fesingle bondZnO/HY is a composite catalyst which is able to induce a combined methanol synthesis and MTG (Methanol-to-Gasoline) reaction. To study these unique catalytic behaviors of Fesingle bondZnO/HY, the adsorption and the dissociation of carbon monoxide on Fesingle bondZnO as well as TPR measurements were carried out. Fesingle bondZnO is able to produce hydrocarbons by F-T reaction and methanol. In the absence of zeolite, Fesingle bondZnO exerts its ability for F-T reaction. However, HY diminishes the activity for F-T reaction and hydrocarbons were obtained via methanol formed over the modified Fesingle bondZnO
