According to the steam reforming of dimethyl ether hydrogen reaction system,the calculation of main reaction in the reaction system chemical equilibrium constant temperature relations; Established the reaction system independent equation and thermodynamic equilibrium calculation,the ether,temperature,water than pressure on the influence of the balance.The results show that the engine exhaust temperature can meet steam reforming of dimethyl ether to temperature,and in the temperature than 473 K,water ether than for 2 4,atmospheric pressure conditions can obtain higher dimethyl ether conversion and hydrogen production rate.Reforming gas hydrogen,carbon dioxide,mainly includes and excess water,still contain a small amount of carbon monoxide.
