Thermodynamic investigation of methanol and dimethyl ether synthesis from CO2 hydrogenation

The thermodynamics involved in the catalytic hydrogenation of CO, have been examined extensively, By assuming that methanol and dimethyl ether (DME) a re the main products, two reaction systems each consisting of two pararell reactions were analyzed and compared in terms of the equilibrium yield and selectivity of the useful products, methanol and DME. The calculation resul ts demonstrated that the production of DME allows much higher oxygenate yie ld and selectivity than that of methanol.
