本研究以數值模擬方法，建立整合含親氫薄膜之重組反應器與水氣轉移反應器之分析模式，先針對甲烷重組器結合水氣轉移反應器之影響，進行模擬分析探討。探討之參數包括：燃燒室進氣當量比、燃燒室進氣量、水蒸氣對甲烷之進氣比及甲烷重組反應器之幾何尺寸等。模擬結果顯示，在貧油條件下，增加燃燒室進氣當量比及燃燒室進氣量皆會使甲烷重組器溫度增加，並提升重組反應之甲烷轉化率，但會降低一氧化碳之轉移率。提高水蒸氣對甲烷之進氣比，可提升甲烷轉化率及增加氫氣之產量，同時可提升一氧化碳轉移率。增加重組器與燃燒室之接觸面積，可提升重組反應之甲烷轉化率及氫氣產出濃度。並針對親氫薄膜對產生高純度氫氣效能影響進行研究分析，及探討水蒸氣對甲烷之進氣比對產氫效能之影響。模擬結果顯示，親氫薄膜對產氫有正面效果，可使氫氣產量增多。至於增加重組器之水蒸氣對甲烷進氣比(S/C)，可提升氫氣產出濃度，但實際氫氣產量則會有遞減之趨勢。

The numerical analytical model for the hydrogen production from the methane steam reforming in a hydrogen separation membrane integrated with a water-gas shift reactor has been developed. It has been applied to investigating the effect of the equivalence ratio of the combustor, the inlet flow rate of the combustor, the geometric parameters of the methane steam reformer, and the hydrogen separation membrane on the performance of purified-hydrogen production from a methane steam reformer. In addition, effects of the steam-to-carbon ratio of the reformer on the production of hydrogen are examined. The simulation results obtained from the present study show that in fuel-lean conditions, as the equivalence ratio and the inlet flow rate of the combustor increase, the temperature of the reformer is raised, promoting the methane steam reforming but reducing the conversion rate of carbon monoxide. A higher steam-to-carbon ratio of the reformer increases the methane conversion rate, the production rate of hydrogen and the conversion rate of carbon monoxide. Increasing the contact area between the combustor and the reformer also raises the methane conversion rate and the production rate of hydrogen. The membrane has a positive effect on the hydrogen generation, resulting in more the hydrogen production. In a membrane reactor, a higher steam-to-carbon ratio of the reformer leads to a higher output of hydrogen concentration. However, production rate of hydrogen goes in a reverse direction with an increasing steam-to-carbon ratio.
