摘要：

An analytical solution for the stepwise cyclic mass transfer problem is presented. The external fluid-film resistance reduced the linear driving force (LDF) mass transfer coefficient significantly at small θc. The dual resistance model improves the prediction of LDF mass transfer coefficients as compared with the rigorous model of Raghavan et al. A simple expression, Bim(min) can be used to assess the importance of film resistance in a rapid pressure swing adsorption process.
