摘要:	本研究探討濾心式活性碳纖維模組之多成份吸附動態與貫穿曲線，模擬過程包括數學模式之建立以及數值解法。完成之數學模式含有非線性偏微分方程組，經以後向差分法，將偏微分方程組改為常微分方程組，並以Mathworks公司之simulink軟體進行模擬。本模擬系統之測試首先以單成份甲苯進行，貫穿曲線模擬之結果與台碳公司實驗結果吻合度極佳。多成份系統模擬，為方便和文獻結果比較，先以雙成份系統之模擬為主，完成以活性碳顆粒及纖維為吸附材之模組計算，模擬之貫穿曲線趨勢和文獻中以活性碳顆粒為吸附劑之填充床式實驗結果雷同。唯台碳公司多成份系統實驗尚未完成，暫時無法印證本研究之模擬結果之準確性。三成份以上之模擬計算和二成份類似，本模擬系統可直接應用之。 This study simulates the dynamics of the multi-component adsorption of activated carbon fiber(ACF) cartridge. The breakthrough curves will be obtained and compared to available experimental data. A nonlinear partial differential equation set(PDEs) were obtained. Numerical approach using backward difference was taking to resolve the PDEs into ordinary differential equation set(ODEs) which are solved successfully using a commercial dynamic simulation package, Simulink, developed by the Mathworks Inc. To verify the simulation model, the breakthrough curves for single component adsorption were obtained and compared to experimental data from previous study. Good agreements indicate the success in modeling. Further calculations were done for two-component adsorption. Breakthrough curves were obtained. Experimental work is underway to verify the model further. To remedy the handicap, experimental breakthrough curves for a two-component adsorption in a packed bed using granular activated carbon as adsorbent were compared with the results from this study. Similar trends in breakthrough curves were observed. This simulator can certainly be applied to simulate the adsorption of three or more component as designed.
