一、前言碳分子筛物质可用子变压吸附技术来分离空气。传统的分了筛功能估测方法有:吸附气体重量分析法,得到特定的碳的吸附容量;以及为比较气体分离的动力学选择性而建立起来的气体吸附率的经验测定法。变压吸附方法分离O_2和N_2的原理在于两种气体在碳分子筛上的吸附速率差异。O_2动态直径为0.346mm,而N_2为0.364mm。对工业碳分子筛的孔结构进行选裁,使之吸附氧的速率高于吸附氮。利用这种速率的差
First, the preface carbon molecular sieve material available sub-pressure swing adsorption technology to separate the air. Conventional methods for estimating sieve function include adsorbed gas gravimetric methods to obtain specific carbon adsorption capacities and empirical determination of the gas adsorption rates established to compare the kinetic selectivity of gas separations. The principle of the pressure swing adsorption method to separate O 2 and N 2 lies in the difference of the adsorption rates of the two gases on the carbon molecular sieve. O 2 has a dynamic diameter of 0.346 mm and N 2 of 0.364 mm. The pore structure of industrial carbon molecular sieve selection, so that the adsorption rate of oxygen higher than the adsorption of nitrogen. Take advantage of this rate difference
