摘要：

The effect of initial concentrations of substrates, temperature and pressure on the formation of both methanol and dimethyl ether at the chemical equilibrium was described. From the results obtained, it can be seen that relatively low temperatures and moderate pressures lead to the high DME yield at the chemical equilibrium, Low initial concentrations of carbon dioxide and the higher initial concentrations of hydrogen than stoichiometric ratio for methanol formation are advantageous for the direct synthesis of dimethyl ether from CO2 and H-2.
