Characterization of CuO/ZnO/Al2O3 Catalyst for Methanol Synthesis

The property of CuO/ZnO/Al2O3 catalysts for methanol synthesis was investigated by means of XRD, H2-TPR and DTG. The results show that the thermal activity of the self-made CuO/ZnO/Al2O3 catalyst is better than the commercial catalyst C302 and displayed stable property after 180h application. The catalyst calcinated revealed strong interaction between CuO and ZnO, and the dispersion of CuO crystal particular was uniform. There was a small amount of carbon deposition on the surface of CuO/ZnO/Al2O3 catalyst after synthesis reaction. For synthesis of methanol with self-made catalyst in fixed reactor from the analog components of reformed bluecoke furnace gas, the space time yield and selectivity of coarse methanol respectively reached 1.5451 g·g-1·h-1 and 99.6143% under the conditions of temperature of 240°C, pressure of 5.5MPa and space velocity of 12000h-1.
