Abstract:
Three Cu/Zn/Al catalyst samples were prepared by a co-precipitation method by changing the concentration of the initial solution and also presiptation speed. The catalysts were characterized by BET surface area, X-ray diffraction (XRD) and temperature programmed reduction (TPR) measurement techniques. All catalysts were tested for methanol synthesis activity in fixed-bed reactor under conditions similar to that of commercial operation. In this study, methanol synthesis catalysts have been made using more concentrated solutions and also higher precipitation rate and their performance was compared with a reference catalyst. Increase of concentration of primary solutions and high speed copercipitation decreased catalyst performance slightly but catalysts produced to the this methods still had relatively adequate performance compare industrial catalysts
