本研究開發了一新型之甲醇蒸汽重組產氫整合系統，此系統以甲醇蒸汽重組器為主體，搭配氫氣燃燒器以及蒸發器；重組器與燃燒器皆為觸媒填充床式反應器，分別選用銅鋅觸媒以及白金觸媒催化反應，蒸發器則由四根紅銅溝槽管所構成，系統設計上採用類似殼管式熱交換器之設計，將燃燒產生之熱量供給蒸發器與重組器使用。為改善觸媒床因低熱導率與化學反應速率不一造成之不均溫現象，本系統埋放一高熱導率之二相熱傳元件熱管於重組器中軸。實驗於多組條件下進行，並且鑽破重組器內熱管使之無效化，以比較埋放有效熱管與無效熱管之反應器性能差異，亦針對部分狀況進行重複性驗證，證明此研究實驗數據之重複性良好。整體而言，系統之甲醇轉化率隨著進料流量之降低以及反應溫度之提高而上升，產物一氧化碳濃度則與甲醇轉化率呈現正相關，而水碳比降低會使甲醇轉化率略為下降，產物一氧化碳濃度則明顯上升；有效熱管反應器於進料流量0.6 ml/min、水碳比1.5、反應溫度250℃之條件下，甲醇轉化率可達85%，產物一氧化碳濃度僅約0.60%；而將熱管無效化後，各反應條件下之甲醇轉化率皆有所下降，下降幅度約為5%至8%，產物一氧化碳濃度則無明顯變化。

This study presents a novel methanol steam reforming hydrogen production system. The system encompasses a methanol steam reformer, a hydrogen combustor, and an evaporator. Both the reformer and the combustor are packed bed catalytic reactors, using copper-zinc catalyst and platinum catalyst, respectively. The evaporator is composed of four copper grooved tubes. The system design is similar to a shell-and-tube heat exchanger, which supplies the heat generated by combustion to the evaporator and reformer. Due to the low conductivity of the catalyst particles and the uneven chemical reaction rate, a heat pipe is embedded in the center of the reformer to improve the temperature uniformity of the reformer. The experiment is carried out under multiple sets of conditions. After the tests, the heat pipe is deactivated and the system is retested to compare the performance with an effective heat pipe and an ineffective heat pipe. On the whole, the methanol conversion rate of the system increases with decreasing feed flow rate and increasing reaction temperature, and the product carbon monoxide concentration is positively correlated with the methanol conversion rate. With a decrease in steam-to-carbon ratio, the methanol conversion rate decreases slightly, and the product carbon monoxide concentration increases significantly. With an effective heat pipe, the methanol conversion rate can reach 85% and the product carbon monoxide concentration is only about 0.60% under the conditions of a feed flow of 0.6 ml/min, a steam-to-carbon ratio of 1.5 and a reaction temperature of 250℃. With an ineffective heat pipe, the methanol conversion rates under all reaction conditions decrease by 5% to 8%, with insignificant change in carbon monoxide concentration.
