Dimethyl Ether Synthesis via Methanol Dehydration over …

N2 - 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, 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.

N2 - The results of the development of combined process for production of dimethyl ether (CuO/ZnO/Al2O3) and methanol dehydration (g-Al2O3, zeolite (ZSM-5 type) with a silicate modulus (M}) 20, 30, 60, 80, 100, and 200) are presented. The experiments on the influence of the catalysts loading and catalytic conditions were carried out (P=3 MPa, H2/CO=2, T=553 K). It was established that the use of ZSM-5 zeolite catalysts with silicate modulus of 30 allows obtaining the yield of dimethyl ether up to 39%. It was stated that catalytic systems were stable during 180 h.

Any solid biomass including for example agricultural, city and industrial waste can be used to make synthesis gas using techniques similar to its production from . More recent developments includes a plant in the Netherlands, which is using liquid propane-1,2,3-triol (glycerol), a by-product from the production of , from animal fats and vegetable oils.
