【Abstract】 The kinetic parameters in the purification of 6# solvent naphtha from aromatics have been studied by using selective adsorption on 13 X zeolite. The model for calculating breakthrough curve of linear equilibrium system can be used to simulate the experimental data. The simulating results are in fine identity with the experimental data. On the basis of those, the kinetic parameters and their rules of variation were obtained. The adsorption process in the experimental conditions can be considered as external diffusion control. All the results are valuable for the design and operation of the commercial device.更多还原
