| Summary: | 碩士 === 元智大學 === 機械工程學系 === 96 === A processing simulator with water flow and combining with a methanol catalytic combustor was used to simulate experimentally the heating condition of reformer. Accumulating the water flow phase change and temperature difference between the input and output conditions of the simulator can show the exacted heat absorption from combustor. Pt-Al2O3 catalyst pellets were aligned in the flow channel of the reactor. The temperature of combustor raises from room temperature to 270℃ within 20 min without assistant heater under the mixture ratio of combustion equivalence about 0.86.
Results show that the simulator absorbs about 67% of total exothermic reaction heat, LHV. 23% of exothermic reaction heat has been taken away by the exhaust products. Controlling the mixture of catalytic combustor near stoichiometry condition can reduce the waste exhaust heat. And, the total surface of the combustor and simulator release 10% of exothermic reaction heat to the surrounding. The heat transfer property of interface material between combustor and simulator can reduce the temperature difference, and increases the thermal efficiency.
