| Summary: | 碩士 === 國立中興大學 === 機械工程學系 === 94 === The purpose of this study is to design a system of autothermal reformer. It takes methanol, water and air as reformed fuel, and then using the E.F.I. (Electric Fuel Injection) system of motorbike engine to control the feeding of methanol reformer. Furthermore, it uses commercialized catalyst MDC-3 that is produced by the SUD-CHEMIE Company. And the catalyst is spread on the stainless steel honeycomb carrier of the motorbike, which is reacted with the methanol. At the beginning of the reaction of the reformer’ start, we implanted the firing system of ignition plugs of motorbike into basic reformer, and we use function generator to provide CDI (Capacity Discharge Ignition) the signal of firing which can make ignition plugs to produce miss fires, then it can burn the methanol to produce the stable fire to supply the heat resource that this experiment needs.
As to the result of this experiment, we can adjust it S/C ratio and O/C ratio. When the feeding rate of methanol is 0.134 mol/min、S/C=0.209、O/C=1.263, the start-up time is about 5 minutes; when the feeding rate of methanol is 0.134 mol/min、S/C=0.209、O/C=0.379, the ratio of production of H2 can reach 32 (vol %)；and when the feeding rate of methanol is 0.153 mol/min、S/C=0.183、O/C=0.444, the ratio of production of H2 can reach 0.142 mol/min.
