本文以超临界流体氩、甲烷和氮气为例，介绍并讨论了这些流体在活性炭Norit R1（Norit公司，德国）和SCS-3（ISPE，基辅）在不同温度至50 MPa压力下的吸附分析结果。在本文中还描述了测量装置的工作原理。使用三参数等温方程来表示吸附平衡。等温方程基于物理模型概念，该概念已用于模拟压力高达 15 MPa 的吸附过程。
In the present work the supercritical fluids argon, methane and nitrogen were picked out as examples, and the results of analysis concerning the adsorption of these fluids at activated carbon Norit R1 (Norit company, Germany) and SCS-3 (ISPE, Kiev) at different temperatures up to a pressure of 50 MPa are presented and discussed in this paper. The principle of working of the measuring device is described in this context as well.A three-parameter isothermal equation is used to represent the adsorption equilibrium. The isothermal equation is based on a physical model concept which has already been used for the modelling of adsorption processes with a pressure up to 15 MPa.
