Determination Of The Effects Of Catalyst Components On The Total Oxidation Of Methane In Zeolite Supported Catalysts Prepared By The Impregnation Method

In this study total oxidation of methane was studied. The effect of zeolite support type, catalysts components on the characteristic and catalytic properties of the catalysts were determined. For this reason, SAPO34 and Zeolite 13X were used as zeolite support. PdO, CeO2, ZrO2 catalysts components were used as active component and as promoter component. Characteristic properties were determined by using X-Ray Diffraction, N2 Physisorption and Scanning Electron Microscopy analysis. According the characteristic results, to obtain high surface area SAPO34 should be chosen as support. Total methane oxidation catalytic activity studies showed that, like characteristic properties the best results in catalytic activity studies were obtained from SAPO34 zeolite supported catalysts. In this study PdO-ZrO2/SAPO34 catalyst is determined as the most active catalyst for total oxidation of methane. Based on the results, it can be said that the internal interaction between PdO and ZrO2 is better than the internal interaction between PdO and CeO2, and that the PdO and ZrO2 pair is more compatible for methane oxidation in the support structure
