Abstract

Direct synthesis of hydrocarbons through CO2 hydrogenation was studied over hybrid catalysts composed of methanol synthesis catalysts (CuO/ZnO/ZrO2) and zeolites (HZSM-5, SAPO-34). At around 350°C, new peak due to the medium acidity appeared during the NH3-TPD of hybrid catalyst, and the areas of these new peaks were well correlated with the hydrocarbon yields in CO2 hydrogenation. The appearance of the new NH3-TPD peak was attributed to the interaction between CuO/ZnO/ZrO2 and SAPO-34, which leads to the mutual changes in acidity of zeolite and reducibility of metal oxides. This is an abstract of a paper presented at the 13th International Zeolite Conference (Montpellier, France 7/8-13/2001).
