Objective To establish a mathematical model of molecular sieve concentrator with pressure swing adsorption, so as to explore the effects of various factors influencing the mole fraction of oxygen. Methods Hypothesis was made based on the actual system, and the physical model was expressed by mathematical model. The thermal effect during adsorption was not taken into consideration. The binary Langmuir equilibrium adsorption equation was adopted to describe the dynamic property between the gas and adsorbent. The linear driving force (LDF) model was applied to describe the mass transfer rate. Numerical solutions were obtained by finite difference method. The effects of parameters, such as the pressure and velocity of inlet gas, cycle time, on the performance of the system were analyzed. Results Under certain circumstance, mole fraction of oxygen increases with the decrease of velocity and the increase of pressure of inlet gas. The increase of the velocity of purge is helpful to mole fraction of oxygen, but can lead to lowering down of O 2 recovery rate. Conclusion All the factors influencing mole fraction of oxygen should be considered simultaneously. Onboard oxygen generating system can satisfy the request of inlet pressure.
