本文在实验研究烷烃中少量芳烃的固定床吸附动态过程的基础上，进行模型化计算。分别用线性推动力和孔扩散两种固定床吸附模型，拟合得出总传质系数、液膜传质系数和孔扩散系数。两种模型的拟会计算结果表明；在本文的实验条件范围内，传质推动力可用线性推动力来表示。总传质阻力由液膜传质阻力和颗粒相传质阻力的共同作用而形成，它随着温度、浓度和流量的降低而增加。孔扩散系数与流量无关。 Based on the experimental study on the fixed bed adsorption dynamic process of a few aromatic hydrocarbons in alkanes, the model calculation was carried out. The two kinds of fixed bed adsorption models with linear driving force and pore diffusion were respectively fitted to obtain the total mass transfer coefficient, liquid mass transfer coefficient and pore diffusion coefficient. The simulation results of the two models show that in the experimental conditions of this paper, the mass transfer driving force can be represented by the linear driving force. Total mass transfer resistance is formed by the combined effect of liquid mass transfer resistance and particle phase mass transfer resistance, which increases with decreasing temperature, concentration and flow rate. Pore ​​diffusion coefficient has nothing to do with the flow.
