Innovative solutions are required to reduce carbon dioxide emissions from energy production processes. Here, we propose to develop a multi-functional membrane reactor using innovative methods to produce two different novel catalytic hollow fibre membranes consisting of an outer separation layer integrated with inner porous substrate where an appropriate catalyst is deposited. The separation layers of the two membranes are permeable to oxygen and hydrogen, respectively. Under reaction conditions methane as fuel will be fed to inner surface of the oxygen permeable membrane and air to the outer surface. Oxygen transport across the membrane will react with methane resulting in syngas production on the partial oxidation catalyst deposited on the inner porous support of the membrane. The resultant products, i.e. CO and H2 are then mixed with steam and fed into the inner surface (deposited with a water-gas-shift (WGS) catalyst) of the hydrogen permeable membrane where both the WGS reaction and H2 permeation take place simultaneously, resulting in a pure H2 permeated stream and a CO2 enriched retentate stream, which is ready for sequestration.

需要创新的解决方案来减少能源生产过程中的二氧化碳排放。在这里，我们建议使用创新方法开发多功能膜反应器，以生成两种不同的新型催化空心纤维膜，该催化空心纤维膜由与内部多孔底物集成的外部分离层组成，并在其中沉积了适当的催化剂。两个膜的分离层分别渗透到氧气和氢中。在反应条件下，甲烷作为燃料将被馈入氧气渗透膜的内表面，并将空气送入外表面。跨膜的氧转运将与甲烷反应，从而在沉积在膜的内多孔支撑上的部分氧化催化剂上产生同步催化剂。然后将所得的产品（即CO和H2）与蒸汽混合，并将其馈入氢渗透膜的内表面（沉积在氢气中的水流偏移（WGS）催化剂）中，同时进行WGS反应和H2渗透率都会发生，从而使纯H2渗透的流渗透到纯净的H2渗透流，并以浓缩的含量富含静止的溪流，以获取富集的序列。
