Abstract

Methanol synthesis catalyst was extensively investigated with changing various promoters and supports, also by changing preparation conditions of synthesis catalyst. In this work, the Cu/ZnO/Al2O3 catalysts were prepared by two methods, co- precipitation and sequential precipitation techniques. The catalysts were characterized by using XRD, XRF, BET, TPR, TGA techniques and the active site of catalysts were determined by N2O adsorption. The percentage of Cu, Zn and Al were also determined by atomic absorption technique. The total surface area of catalyst produces by sequential precipitation showed twice as many of the catalyst produces by co- precipitation method and showed higher activity.
