Abstract
The operating principle of the OnBoard Oxygen Generating System (OBOGS) and the basic theory of enriching oxygen with Pressure Swing Adsorption (PSA) are briefly introduced. A nonisothermal adsorption model to simulate the dynamic PSA process has been established with consideration of the factors of mass transfer, heat transfer as well as pressure variation in the column. In the model, linear driving force for adsorption rate and mixed Langmuir isothermal theory for calculating equilibrium amount adsorbed are adopted. The adsorption process of adsorption bed is simulated and the result is analyzed.
