薄膜反應器這個觀念，早在四十多年前便已產生。其原理主要為在傳統柱狀流反應器中加了一層薄膜，使得反應器同時具有反應和分離之功能。如此可以提高反應的轉化率及減少分離成本。本文主要是以數值模擬，來探討薄膜反應器(membrane reactor)之特性。將觸媒填充在管層的觸媒填充式薄膜反應器中改變反應進料層(feed-side)和滲透層(permeate-side)壓差、進料流量、沖洗氣體流量、薄膜厚度及氧醇比等操作條件，來暸解這些操作條件對於反應的影響。以有限差分法有效率地計算反應器內部濃度及流動情形，增進我們對甲醇蒸汽重組(steam reforming of methanol)與甲醇部分氧化(partial oxidation of methanol)反應在本反應器中反應進行的瞭解。 The idea of membrane reactor was proposed forty years ago. A membrane is inserted into a traditional reactor to make reaction and separation simultaneously occur in the reactor which can improve the conversion and reduce the separation cost. This study utilizes the finite difference method to simulate steam reforming of methanol and partial oxidation of methanol in inert membrane reactor with catalytic pellets in the feed-side chamber (IMRCF). The influence of operating variables, such as pressure, feed flow rate, sweep gas flow rate, membrane thickness, O2/CH3OH ratio etc. on the performance of system is studied.
