摘要:
采用模板法合成有机氧化硅空心球(hollow organosiliceous sphere, HOS),以正己烷为吸附对象,考察了载气流速,正己烷浓度和湿度对HOS动态吸附的影响,并与商品化的活性炭(activated carbon, AC)进行对比。结果表明HOS有较好的动态吸附容量,吸附稳定性高,对正己烷的吸附选择性较高。同时利用Logistic模型的回归公式模型对HOS和AC动态吸附过程的拟合,拟合曲线与实验结果具有高度相似性,可以较为准确地预测VOCs 动态吸附穿透曲线。
Abstract:
Hollow organosiliceous sphere(HOS)was synthesized by the template method, the dynamic adsorption performances for n-hexane under different n-hexane concentration, the flow rate of carrier gas, and humidity were studied with activated carbon(AC)as reference. The experimental results show that HOS has higher n-hexane equilibrium adsorption capacity, stability, and higher selectivity for n-hexane as compared to AC. At the same time, the dynamic adsorption processes on HOS and AC could be simulated by Logistic model. Fitting curve of Logistic model had high similarity with the experimental results, which could be used in the prediction of breakthrough curves HOS and AC.
