• 中文摘要： 在本文中,主要探討在液-固-液批式反應器中之三相觸媒催化反應之動態行為,在建立數學模式時,反應物之整體相之質量傳送,在觸媒顆粒中反應物經由孔洞之擴散,以及反應物之本質化學反應皆同時一齊考慮為影響反應產物之主要因素。在本研究中,固體顆粒及水相反應物在反應之開始時,就已經放置於反應器中。因此,反應可藉著添加有機相反應物於反應器而開始進行,反映系統之質量傳送阻力及化學反應阻力之相對重要性可以由Thiele modulus及Biot number二個參數來決定,而整個反應系統之動態行為可以將所建立之數學模式利用有限差分法獲得答案,由計算中,三相催化反應之有效因子(effectiveness factor)及視反應速率常數(apparent reaction rate constant)也一齊獲得。
• 英文摘要： In this study, the dynamics of a triphase catalysis in a liquid-solid-liquid batch reactor were investigated theoretically. The mass transfer or reactants in the bulk phases, the diffusion of reactants through pores within the catalyst particle and the intrinsic reactions of the reactants were all considered in formulating the mathematical model. The initial process of the triphase reaction system is that the solid catalyst and the aqueous phase initially exist in the reactor, and the reaction is started by the addition of the organic phase to the reactor. The Thiele modulus and Biot number of the triphase catalytic reaction, which reflect the relative importance of the mass transfer resistance to the reaction resistance, were defined. A solution of the dynamic behavior was obtained by the finite difference method. The calculated effectiveness factor of the triphase catalysis and the calculated apparent reaction rate constant were also investigated.
