摘要：
The mathematical model for a zero length column (ZLC) system has been extended to the practically important situation in which the sorption kinetics are controlled by the combined effect of intracrystal-line diffusion and surface resistance to mass transfer. The validity of the new model is demonstrated by application to experimental data for diffusion of ethane in DDR zeolite. (C) 2011 Elsevier Ltd. All rights reserved.
