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，我们建议开发一个多功能的膜反应器，使用创新的方法来生产两种不同的新型催化中空纤维膜组成的外部分离层集成与内部多孔基板，其中适当的催化剂沉积。两种膜的分离层分别可渗透氧气和氢气。在反应条件下，甲烷作为燃料将被供给到氧气可渗透膜的内表面，空气供给到外表面。穿过膜的氧输送将与甲烷反应，导致在沉积在膜的内部多孔载体上的部分氧化催化剂上产生合成气。然后将所得产物，即CO和H2与蒸汽混合并进料到氢可渗透膜的内表面（沉积有水煤气变换（WGS）催化剂）中，其中WGS反应和H2渗透同时发生，产生纯H2渗透流和富含CO2的渗余物流，其准备用于封存。
