    Abstract

    The mechanism of the H2, CO, CO2, CO3OH, (CH3)2O interaction with the surfaces of CuO/ZnO/Al2O3 and g-Al2O3 was investigated using temperature-programmed desorption method with mass spectrometry detection. It was shown that desorption of the main process components takes place in the temperature range between 373 and 673 K, which corresponds to the temperature range for catalytic studies. Methanol dehydration takes place over the surface of g-Al2O3 catalyst with formation of dimethyl ether at Tmax = 553 K{cyrillic}, which is the optimal temperature for synthesis of dimethyl ether from CO and H2 over industrial catalysts with layered loadings. The desorption energies of the gases were calculated.
