Novel Catalytic Membrane Micro-reactors for CO2 Capture via Pre-combustion Decarbonisation Route

需要创新的解决方案来开发新的二氧化碳捕获系统。在这里，我们建议开发一种新型的催化膜微反应器，用于捕获二氧化碳，同时从甲烷(或煤/生物质)等化石燃料中低温生产超纯氢。这涉及到我们最近开发的几种先进催化剂和膜技术的组合。所开发的新型膜由不对称中空纤维载体的Al_2O_3组成，在其上沉积一系列改性的Ni(Fe，Cu)、Ru或Rh催化剂，并在其背面涂覆一层Pd或Pd-Ag合金膜。这种制备具有活性金属催化剂和氢分离层的氧化物载体的方法迄今为止还没有尝试过，以用于化石燃料重整和二氧化碳捕获的综合功能。这种新型膜微反应器的主要优点是，由于操作温度低和氢的高度选择性渗透，可以在没有催化剂失活的情况下实现高甲烷转化率，从而使催化剂能够长期稳定。这项工作将涉及高度多学科的努力，与来自英国和中国的世界领先团队一起研究上述一些关键挑战。该提案的独特之处在于，受雇于该助学金的PDRA和博士生将前往合作机构接受催化、膜、建模和系统集成方面的扩展培训，这将增强我们的研究能力，并增加受雇研究人员的就业能力。

Innovative solutions are required to develop new systems for CO2 capture. Here, we propose to develop a novel catalytic membrane micro-reactor for capture of CO2 and at the same time producing ultrapure hydrogen at low temperatures from fossil fuel such as methane (or coal/biomass). This involves a combination of several advanced catalysts and membrane technologies recently developed by us. The novel membrane to be developed consists of Al2O3 in the form of an asymmetric hollow fibre support onto which a series of modified-Ni (Fe,Cu), Ru or Rh catalysts will be deposited with a Pd or Pd-Ag alloy membrane coated onto the opposite side. Such an approach of fabricating an oxide support with active metal catalysts and a hydrogen separation layer for a combined function of reforming of fossil fuel and CO2 capture has not been attempted to date. The major advantage of this novel membrane micro-reactor is that, due to the low operating temperature and highly selective permeation of H2, high methane conversions can be achieved without catalyst deactivation enabling long term stability of the catalysts. The work will involve a highly multi-disciplinary effort with world-leading groups from UK and China to examine a number of key challenges mentioned above The proposal is distinctive in that the PDRAs and PhD student employed on the grant will travel to collaborating institutions for extended training in catalysis, membranes, modelling and system integration which will strengthen our research capability and increase the employability of the employed researchers.
