摘要

甲醇蒸汽重組反應是吸熱反應，必須額外提供熱源，直接使用甲醇燃燒觸媒方式供熱，比起採用電加熱方式，不但提升能源效率，還可以簡化系統設計。本研究利用高活性的甲醇燃燒觸媒（Pt/Al2O3），在室溫環境可以催化甲醇水溶液進行燃燒，不需要額外的電加熱系統。平板式微流道甲醇燃燒器，從室溫起燃只要2-3分鐘，燃燒區的最高溫可以達到350°C，甲醇的燃燒效率超過99.9％以上，燃燒的最終產物為二氧化碳與水氣。

The methanol steam reforming (SRM) system must be heated because the SRM reaction is endothermic. In this regard, using catalytic combustors as the heating device is a better choice than using electrical heaters. We have successfully demonstrated that it is possible to obtain acceptable start-up times for a methanol reformer without utilising electrical energy to heat the components of the system. The temperature of the micro-channel plate of the catalyst bed was over 350°C (local maximum temperature) after start-up of 2-3min. Both conditions showed greater than 99.9% methanol conversion to H2O and CO2. This implies that degradation of Pt/Al2O3 was insignificant during the experiment.
