Abstract
- The work consists of a detailed study of the interaction of CO, H2, CO2, CH3OH, dimethyl ether (DME) with the surface of the catalyst in the one-step synthesis reaction of dimethyl ether from synthesis gas. The process of obtaining DME from H2 and CO, synthesis of methanol and its dehydration in the presence of a catalyst consisting of ZnO·Al2O3·ZrO2·CuO ·CaO/bentonite: γ-A12O3 and their layer-by-layer loading were studied. Since methanol synthesis and its dehydration take place simultaneously in one reactor, ZnO·Al2O3·ZrO2·CuO ·CaO/bentonite: γ-A12O3 in the presence of a catalyst a) 1:1, b) 2:3, c) 2:1:2 methods of layer loading are provided. Operating conditions T=290 °C, P=0.5 MPa, CO/H2=0.5, volume velocity 1000 hour −1 pressure, conversion of CO to methanol and DME output in one pass through the catalyst bed were studied.
