A Non-Driving-Force Approximation for Intraparticle Diffusion and Reaction
顆粒內擴散及反應之非驅動力近似式
摘要
本研究推導用於描述因顆粒表面濃度階梯式改變所導致動態行為之非驅動力近似式。近似式所考慮之現象包括顆粒內之吸附、擴散及一次反應。在整個時間範圍內近似式運算結果和準確解均十分吻合。就準確度而言，本研究所推導之近似式優於其他文獻中所發表之相關公式。

A non-driving-force approximation is presented for the description of dynamic response of a spherical porous particle subject to a step change in the surface concentration. Intra Particle adsorption, diffusion and a first-order reaction occurring within the porous particle are considered in the present formula. Excellent agreement between the present approximation and the exact solution was found over the entire time domain. In terms of accuracy, the present approximation is superior to the previously reported ones.
