利用真空吸附法测试了BaX分子筛对二甲苯的等压吸附曲线.实验发现,在室温下该分子筛对M-二甲苯、O-二甲苯、P-二甲苯的吸附曲线和吸附速度是不一样的;同时在分子筛吸附了一定量的水之后,其对二甲苯的吸附曲线和吸附速度发生了明显变化,其中,在水含量为2%时影响最大. The isobaric adsorption curves of p-xylene by BaX zeolite were tested by vacuum adsorption method. It was found that the sorption curves and adsorption velocities of M-xylene, O-xylene and p-xylene were different at room temperature At the same time, the adsorption curve and adsorption rate of p-xylene changed obviously after adsorbed a certain amount of water on molecular sieve, of which the influence was the greatest when the water content was 2%.
