摘要
改进了NWA-Ⅱ型分子筛吸附剂的制备方法，测定了制备的吸附剂的孔结构和液相动态吸附性能。结果表明，改进后的NWA-Ⅱ吸附剂比表面积减小，平均吸附孔径增大，吸附速率变快，其动态吸附容量超过了改进前的NWA-Ⅱ，接近进口吸附剂ADS-34的水平。
Preparation of NWA-Ⅱ molecular sieve adsorbent was modified. The pore structure and liquid dynamic adsorption characteristics of prepared adsorbents were tested. The results indicated that modification could yield the adsorbent with a decreased BET surface area, an increased average pore diameter for adsorption and a much more rapid adsorption rate. As compared to NWA-Ⅱ , the modified NWA-Ⅱ adsorbent exhibited higher adsorption capacity, which is approximately equal to that of imported adsorbent ADS-34.
