Experimental and theoretical study of the temperature-dependence of multicomponent adsorption between -80 °C and +80°C

-80℃~80℃多组分吸附温度依赖性的实验与理论研究

基本信息

项目摘要

The aim of the proposed project is to experimentally investigate and thermodynamically model the temperature dependence of mixture adsorption of chemically similar C2 to C5 hydrocarbons over a wide temperature range between -80°C and +80°C for the first time.Combinations of adsorptives and adsorbents are investigated, which differ in their fundamental adsorption mechanisms and therefore provide deeper insights into mixture adsorption, e.g. n-alkanes and n-alkenes of the same chain length combined with sodium-based and (partially) calcium-exchanged zeolites. For these systems, single-component adsorption isotherms and mixture isotherms are determined experimentally.The experimental results, the underlying mechanisms and the temperature dependence of the interactions are to be analysed and discussed. To describe the experimental data, (temperature-dependent) thermodynamically consistent models are to be applied, modified or further developed if necessary. This includes established methods like IAST, but also, if these do not show sufficient accuracy, more complex models like RAST with corresponding activity coefficient models. These models also serve to gain a deeper scientific understanding of the temperature dependence of multicomponent adsorption to be able to predict it and transfer it to other systems.Finally, the temperature dependence of the adsorptive separation will be quantified on the basis of selectivity parameters in order to optimize process parameters for technical separations.
该项目的目的是首次在-80 ° C和+80 ° C之间的宽温度范围内实验研究和模拟化学相似的C2至C5烃的混合物吸附的温度依赖性。研究了吸附剂和吸附剂的组合,其基本吸附机理不同,因此提供了对混合物吸附的更深入了解,例如相同链长的正构烷烃和正构烯烃与钠基和(部分)钙交换沸石的组合。实验测定了这些体系的单组分吸附等温线和混合吸附等温线,并对实验结果、相互作用机理和温度依赖性进行了分析和讨论。为了描述实验数据,(温度依赖性)化学上一致的模型将被应用,修改或进一步开发,如果必要的话。这包括已建立的方法,如IAST,但如果这些方法不能显示足够的准确性,则还包括更复杂的模型,如RAST和相应的活度系数模型。这些模型还有助于对多组分吸附的温度依赖性有更深入的科学了解,以便能够预测并将其转移到其他系统。最后,吸附分离的温度依赖性将根据选择性参数进行量化,以便优化技术分离的工艺参数。
