Adsorptions of formaldehyde on 5A. ZSM-5,13X,CaX zeolites were investigated and compared,Results indicated that CaX zeolite had a significant increase in the adsorption capacities and prolongation of breakthrough time on removing of formaldehyde.

• 然后对5A、ZSM-5、13X、 CaY型沸石分子筛吸附甲醛的性能进行了研究,发现CaX沸石对甲醛的吸附量较高,穿透时间延长。
