Chemical Recuperation of Low-Grade Exhaust Heat by Steam Reforming of Dimethyl Ether

چکیده
For the new process of effective utilization of energy, chemical recuperation of low-grade exhaust heat by steam reforming of dimethyl ether (DME) was proposed. Steam reforming of DME is an endothermic reaction as; DME + 3H2O + 122[kJ/mol] → 6H2 + 2CO2. If this reaction could be proceed by exhaust heat below 573 [K], those exhaust heat which is wasted to ambient would be recuperated as the fuel with increasing exergy. In this study, a fixed bed type reactor was adopted experimentally. Catalytic activity for steam reforming of DME was estimated in the atmospheric pressure, the S/C=1.55 and reaction temperature of 523 [K] to 573 [K] as a practical condition. As a result, highly conversion of DME was confirmed around 523 [K].

Steam reforming integrated with oxidation of methanol was considered with numerical simulation. The parallel micro-channels with circular cross sections were used. Because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. Hence, the approximation of a cylindrical channel is appropriate. Effect of this changing in cross section was considered and results ...
