| 摘 要： | 采用动态吸附法研究了323K和353K下CS2与惰性混合气体在硅胶上的吸附性能,并采用多个模型方程对数据进行了回归。从回归模型可以看出,实验数据能够较好的满足Langmuir-Freundlich方程。采用较温和的再生条件,在413K时考察了再生吹扫氮气气体总量对硅胶吸附容量的影响,氮气流量300mL/min,吹扫20~25min时较为适宜,硅胶损耗很小,硅胶多次再生的穿透吸附容量较为稳定。研究了吸附压力对CS2穿透性能的影响,CS2分压越大到达穿透点的时间越长。研究结果为工业采用硅胶预脱除含CS2气体提供参考。 |

| Abstract: | Dynamic adsorption penetration properties of CS2 and inert gas mixture on silica gel at 323K and 353K were studied,with a number of model equations regressions. Results showed that the experimental data can better fit the Langmuir-Freundlich equation. Under moderate regeneration conditions,impact of total renewable purge nitrogen gas on adsorption capacity of silica gel at 413K was studied,it was found that nitrogen flow rate of 300mL/min and purge gas in 20~25min would be more appropriate,with more stable ... |
