Effect of metal oxide additives on the properties of Cu/ZnO/Al2O3 catalysts in methanol synthesis from syngas

Keywords: Methanol synthesis, Cu/ZnO/Al2O3 catalysts, metal oxide additives
The Cu/ZnO/Al2O3 catalysts, prepared by co-precipitation method, has been modified by adding small amount of Mn, Mg, Zr, Cr, Ba, W and Ce oxide using design of experiments (1/16 full factorial design). The structure and morphology of catalysts were studied by X-ray diffraction (XRD) and Surface area (SBET). Performance of the prepared catalysts for CO/CO2 hydrogenation to methanol was evaluated by using a stainless steel fixed-bed reactor at 5MPa and 513 K.
The oxide additives were found to influence the catalytic activity, dispersion of Cu, Cu crystallite size, surface composition of catalyst and stability of catalysts during their operations. The results showed that the Mn, Zr and Ba promoted catalysts have high performance for methanol synthesis from syngas.
