For the new process of effective utilization of energy, the process of recovery of exhaust heat energy with steam reforming of dimethyle ether (DME) proposed. Steam reforming of DME is an endothermic reaction as; DME + 3H2O+122[KJ/mol] → 6H2O +2CO2-122.5KJ/mol.So,if the exhaust heat energy would be used for the reforming reaction, the exhaust heat energy could be recovered as hydrogen, fuels of high quality. In this study, Fundamental experiment for steam reforming of DME has been done with fixed bed reactor, changing experimental condition; W/F, temperature, H2O partial pressure and DME partial pressure. Reaction rate equation was formulated with experimental results. DME conversion with the obtained equation and DME conversion with experiment was average error with 0.04[-]. Next, Quantity of catalyst for reactor was compared with device scale of exhaust heat source; gas engine with reaction rate equation obtained. Quantity of catalyst was
fully smaller by comparing to device scale of exhaust heat source.
