Equilibrium conversion degrees in direct synthesis of dimethyl ether from CO and H-2

The influence of temperature, pressure and initial molar ratio of substrate s on the equilibrium conversion degrees in direct synthesis of dimethyl eth er (DME) from CO and H-2 has been established. The significant influence of the temperature on the equilibrium content of the product has been found. Modelling results have shown that the one-step synthesis of DME from CO and H-2 in higher pressures and relatively lower temperatures (T < 550 K) is b eneficial because of the high selectivity and yield of the main process pro duct.
