项目摘要
The removal of light hydrocarbons from exhaust air or process gas is important in multiple environmental and technical applications, but cannot be efficiently realized when it comes to separation of trace quantities. Even adsorption processes, though commonly used for removing trace quantities, do not provide the required separation efficiency under typical process conditions (ambient temperature and pressure). That is where the proposed project aims at. By lowering the temperature down to a temperature region of -80 °C to 0 °C we assume an increase of the adsorption capacity of the adsorbents so that trace quantities can safely be removed. But as lowering the temperature leads to an increase of adsorption capacity, the diffusion rate inside the adsorbents pore system decreases. Since there are no reliable data on the magnitude of both effects, the scientific issue of the proposed project is to quantify as to how the loading of the adsorbents increases and how strongly the kinetics decrease in between -80 °C to 0 °C. By a combination of experiments in a fixed bed adsorption reactor and dynamic simulations of the adsorption processes the influence of those opposing mechanisms should be evaluated.
从废气或工艺气体中去除轻质烃在多种环境和技术应用中是重要的,但是当涉及到痕量分离时不能有效地实现。即使是吸附方法,虽然通常用于去除痕量,但在典型的工艺条件(环境温度和压力)下也不能提供所需的分离效率。这就是拟议项目的目标所在。通过将温度降低到-80 °C至0 °C的温度区域,我们假设吸附剂的吸附能力增加,使得痕量可以安全地去除。但随着温度的降低,吸附容量增加,吸附剂孔系统内的扩散速率降低。由于没有关于这两种效应的可靠数据,拟议项目的科学问题是量化吸附剂的负载如何增加以及在-80 °C至0 °C之间动力学下降的程度。通过固定床吸附反应器中的实验和吸附过程的动态模拟相结合,应该评估这些相反机制的影响。
