摘要
为探讨活性炭吸附C40/4有机蒸汽的性能曲线规律,在不同温度288.15K,293.15K和298.15K下实验测试了活性炭C40/4吸附有机气体甲苯和丙酮的吸附性能,基于langmuir等温吸附理论,从吸附动态平衡的角度,理论分析了吸附性能曲线中参数与温度之间的关系,提出一个经验的langmuir等温吸附曲线模型,它能很好地描述不同温度下的有机蒸汽在活性炭上的吸附性能曲线.模型计算值与实验测试值之间的误差小于6%.为确定活性炭吸附有机蒸汽的吸附量提供了有效的计算模式,从而为有机蒸汽吸附过程的设计、预测和优化提供有益的支持.
In order to study the law of the adsorption isotherm of organic vapour on activated carbon C40/4, the adsorption isotherms of toluene and acetone on activated carbon (C40/4) were measured by time integration of the breakthrough curves at 288.15 K, 293.15 K and 298.15 K using an apparatus developed for this purpose. The relationship between these parameters of the adsorption isotherm and the temperature, which is based on the theory of langmuir from the aspect of a dynamic equilibrium, was theoretically analyzed. The experienced adsorption isotherm model, which describes the adsorption isotherm of organic vapour on activated carbon C40/4 at different temperature, was proposed. The experimental data were correlated with the Langmuir adsorption isotherms, which is a fundamental theoretical relation for temperature. An excellent agreement between experimental data and computing data of these equations, whose tolerance is less than 6%, is observed. The mathematical model method offers effective solution for the capacity of organic vapour on activated carbon to forecast and optimize the adsorption process.
