摘　　要：建立了典型的带有一、二级化学反应气液吸收过程的数学模型,然后采用MATLAB的dsolve和ode功能函数,对模型中的液膜内扩散-反应方程和液相主体吸收方程进行求解,部分计算结果还与实验值进行了比较,结果表明MATLAB可实现化学吸收动态过程的快速、高效、准确模拟。Mathematical models for gas-liquid absorption accompanied with first or second order reaction are established. The MATLAB functions dsolve and ode23 are used to find solutions of diffusion-reaction equation governing mass transfer and reaction kinetics within the liquid film and absorption equation concerning the liquid bulk analytically and numerically. Some simulating results are verified by experimental data. The model solving process demonstrates that MATLAB is capable of dynamic simulating for chemical absorption in a straightforward, accurate and high efficiency manner.
