Abstract

The thermal desorption of CO, H2, and CH3OH from the surface of Katalco-58 industrial catalyst for the synthesis of methanol and γ-Al2O3 was studied. Weak interaction of the gases with the surface of samples was observed over the temperature range 75–400°C. The desorption of the gases obeyed the second-order Wigner-Polyani equation. The desorption energies of the gases were calculated. The mechanism of dimethyl ether synthesis was studied.
