A change in the separation of gas mixtures towards clean and energy friendly process technologies is more than desirable. Very promising for this purpose is a process adapted membrane technology. By reference to the industrial relevant case of natural gas conditioning the separation behavior of different porous membranes shall be examined in practical and theoretical experiments and the influence of different parameters on the performance will be tested.Long-term objective is the establishment of a membrane based separation process which is moderated by influences brought from outside to the membrane.The working hypothesis of a pressure driven membrane technology was proven in the first funding period. However, complex coherencies have not been completely enlightened and shall be further examined in practical experiments and simulations. Against this background we think the continuation of the started work is necessary.However, the main goal of the present project proposal is the achievement of a fundamental understanding of occurring processes during the separation of multinary gas mixtures using different porous membranes. Artificial gas mixtures comparable to natural gas - which contain water and carbon dioxide beside alkanes - will be investigated towards adsorption/condensation and permeation. In order to generate a condensed phase for non-condensable gases ionic liquids supported in porous layers will be investigated.

气体混合物的分离朝着清洁和能源友好的工艺技术的变化是非常可取的。 非常有前途的是一种适用于此目的的工艺膜技术。结合天然气调质的相关工业实例，对不同多孔膜的分离性能进行了实际和理论实验研究，并测试了不同参数对性能的影响。本课题的目标是建立一种由外界对膜的影响来调节的膜分离过程。压力驱动膜技术的工作假设在第一个融资期就得到了证实。然而，复杂的相干性还没有得到完全的启发，并将在实际的实验和模拟中进一步检查。在此背景下，我们认为有必要继续开展已开始的工作。然而，本项目提案的主要目标是对使用不同多孔膜分离多元气体混合物过程中发生的过程进行基本了解。与天然气相当的人造气体混合物-除了烷烃外还含有水和二氧化碳-将研究吸附/冷凝和渗透。 为了使不凝性气体产生凝相，将研究多孔层中负载的离子液体。
