Attrition Resistant Catalyst of Direct Dimethyl Ether Synthesis

Abstract:

Direct dimethyl ether synthesis catalysts containing different content of SiO2 are prepared by spray drying method and characterized by XRD, N2 adsorption, and Polarizing Microscope. It is found that the spray drying process improved the spherical of the catalyst particles and the attrition resistance of the catalyst is increased by the addition of SiO2. The SiO2 formed a framework throughout the catalyst and has little effect on the morphology of CuO, ZnO and HZSM-5. The activity of the catalyst shows a little decrease with the SiO2 addition.
