项目摘要
The design of adsorption processes requires thermodynamic data; adsorption isotherms as well as a deep understanding of caloric effects, e.g. adsorption enthalpies. From a scientific point of view the energetic characterisation of molecular adsorption processes, i.e. adsorption mechanisms are of great interest. This comprises the interactions between adsorbed molecules and adsorbent’s surface as well as interactions between molecules in the adsorbed state.The aim of this project is to investigate the type and strength of interactions as well as adsorption mechanisms based on simultaneous measurements of adsorption isotherms and enthalpies. This investigation needs a very systematic choice of adsorbents and adsorptives. The ultimate target is to develop a mathematical model for the calculation of adsorption enthalpies of different adsorptive-adsorbent-combinations. In addition the influence of temperature on adsorption enthalpies will be examined in one system.To realise the project a new measuring device was developed, which is based on a coupling of volumetric measurements of adsorption isotherms and simultaneous calorimetric measurements of adsorption enthalpies.
吸附过程的设计需要热力学数据、吸附等温线以及对热量效应的深入了解,例如吸附热焓。从科学的角度来看,分子吸附过程的能量学特征,即吸附机制是非常有意义的。这包括吸附分子与吸附剂表面之间的相互作用以及吸附状态下分子之间的相互作用。本项目的目的是在同时测量吸附等温线和吸附热焓的基础上,研究相互作用的类型和强度以及吸附机理。这项研究需要非常系统地选择吸附剂和吸附剂。最终目标是建立一个数学模型,用于计算不同吸附-吸附剂组合的吸附热。此外,还将在一个系统中考察温度对吸附热的影响。为了实现这一项目,开发了一种新的测量装置,该装置基于吸附等温线的体积测量和同时吸附热的量热测量。
