Numerical Simulation of CO_2 Removal with Carbon Molecular Sieve for Use in Portable Life Support System / 航天医学与医学工程

ABSTRACT

Objective To establish a numerical model of adsorption and desorption of CO_2 and to study the influencing factors on the removal system. Method A physical model was expressed by mathematical method, then an isothermal adsorption model for simulating molecular sieve was established. Result The working process of a CO_2 removed device was simulated and its result was analized with the established model.The characteristics of the adsorption and desorption was obtained. Conclusion The model describes the processes correctly, the influencing factors like humidity dimension of the bed are considered simultaneously.It remains to be improved by further experimental corrections.
