改性天然丝光沸石对氨的吸附性能

以缙云天然丝光沸石为载体,考察了载体预处理、不同活性组分、负载量等因素对氨、吡啶、二乙胺吸附容量的影响。结果表明,负载CuSO_4对氨的吸附容量明显提高,具有物理吸附和化学吸附双重功能,但吡啶、二乙胺略有下降。随着焙烧温度的提高,其对氨的吸附能力也提高,水份的存在对氨的吸附容量影响不大。

Adsorption of ammonia on modified natural mordenites

The natural morderdte in Jinyun is used as a carrier. The effects of its pretreatment and varities and quantities of the active compositions that it carries on the adsorbing capacity of ammonia, pyridine and diethlamine are studied. It turns out that the adsorbing capacity of ammonia will be highly increased and the adsorption shows both physical and chemical adsorption properties simultaneously, whereas the adsorbing capacity of pyridine and diethylamine will be a little decreased when CuSO_4 is carried. The adsorbing ability of the carrier to ammonia will also be increased when its burning temperature is raised, and the existing water has less effect on the adsorbing capacity of ammonia.
