Abstract:	活性碳纖維 ( activated carbon fiber ) , 因其吸附性能遠優於傳統活性碳顆粒( granular activated carbon )，在工業上之應用極具潛力。常被編織成濾網使用於工業除污方面，而濾心式活性碳纖維模組，其用途廣泛更是製造業者極欲開發之產品。本研究探討濾心式碳纖維模組之吸附動態與貫穿曲線，以實驗及模擬同時進行。研究對象為台碳科技股份有限公司開發之濾心式活性碳纖維吸附系統，模擬參數分別為碳纖維之類型，纖維布編織經緯以及纏繞方法等，最終目的在建立一濾心式活性碳纖維模組之設計軟體。模擬過程包括數學模式之建立及數值解法，數學模式之建立以濾心式模組之MESH ( Material balance，Equilibrium，Summation，Heat balance )架構，責成一含偏微分動態非線性方程組。數值解法採後向差分法將偏微分系統改成一常微分動態差分系統方程組，並以Mathworks公司之Simulink解之。動態模擬結果與模擬貫穿曲線與實驗結果比較，吻合度甚佳。而變更模組參數預測結果則有待進一步證實或修正。未來將建構一完整之濾心式活性碳纖維模組設計軟體。 Activated carbon fiber having a greater adsorption capability than its counter part, granular activated carbon, has gained its acceptance as potential adsorbent in both chemical and pollution control industries. The activated carbon fiber cartridge, one of the most popular applications, has a great market demand in treating polluted air and water, and is receiving much attention from industry. This study investigates the adsorption dynamics and its break-through curve of a filter cartridge manufactured by Taiwan Carbon Technology Co., LTD. (a local manufacturer in Taichung Industrial Park). The controlled parameters are the building material of fiber, the weaving and knitting of the fiber cloth, and the physical dimensions of the cartridge. The ultimate concern is to build up a software package for design purpose. Adsorption dynamics and break-through curve were done through simulation and experiment, respectively. Simulation involves the mathematical modeling and numerical solution. Mathematical model (a partial differential equation set) was derived applying so-called MESH (material balance, equilibrium, summation and heat balance) method. Finite difference method was employed to convert the partial differential equations into an ordinary differential equation set which was solved using Simulink by The MathWorks, Inc. Good agreements between the simulated and experimental results were observed in this study. Predictions based on the derived model, however, required further experimental support.
