摘要:
采用容量法测定温度范围为223.15~313.15 K、压力范围为0~1.5 MPa的乙烯在活性炭上的吸附平衡数据,通过Langmuir模型回归每个温度点的吸附平衡数据。结果表明:Langmuir模型参数饱和吸附量(qm)与温度(T)的关系为线性关系,Langmuir模型常数b与温度的关系符合关系式b=kexp(Ea/RT); 将该关系应用到考虑吸附剂内存在不同吸附位点的双位点Langmuir(DSL)模型,采用DSL模型回归关联实验测定的各个温度点的乙烯-活性炭体系和文献中的吸附平衡数据,结果表明这些关系也适用于DSL模型。
Abstract:
The adsorption equilibrium data of ethylene on an activated carbon at temperatures from 223.15 K to 313.15 K,and pressures up to 1.5 MPa were measured with the volumetric method.The equilibrium data were correlated with Langmuir model at separated temperatures.Results showed that the temperature(T)dependence of Langmuir model parameter adsorption capacity(qm)was linear,and the Langmuir parameter b was in line with the relation of b=kexp(Ea/RT).These dependences were applied to Dual-Site Langmuir(DSL)model.The adsorption equilibrium data of ethylene on activated carbon and the data from the references were correlated with DSL model, and results showed that these dependences could be suitable to DSL model.
