Building upon recent research, demonstrating the synthesis of novel materials that are capable of selectively adsorbing and storing CO2 via novel interactions, this project focusses on the manufacture of materials designed to adsorb CO2 for carbon capture applications. Direct Air Capture (DAC) of CO2 has the potential to become a major emissions mitigation technique in the run-up to a net zero economy (Energy White Paper, UK BEIS). However, progress in this area hinges on designing new materials with ideal characteristics for the process - e.g. high selectivity towards CO2 over all other components of air; high operating capacity; high regeneration efficiency; scalable and economic manufacture. Despite extensive research into DAC systems, optimal materials have not yet been found. This is because prior research has tended to oversimplify the system (e.g. using binary gas mixtures whereas the real composition of air is much more complex) and focussed on only parts of the process. The main aim of this project is to develop a materials screening pipeline that considers realistic operating conditions (e.g. mixtures of multiple components at the correct air compositions, including water, wide range of pressures and temperatures) and covers all stages (material synthesis, screening, laboratory testing and process design). There is also a need to develop rapid screening of materials for DAC processes, and the supervisors are working with NPL on a project to design and implement a process to screen potential materials; this will initially be at the small scale, however, there will be a need to characterise and test these materials at scale. The project complements an iCASE award for Dr Jorge and Prof Fletcher working on the screening of various classes of porous materials for DAC through molecular simulation (activated carbons, porous silicas, RF gels, MOFs), which will be validated against experimental data obtained under realistic conditions at both NPL and Strathclyde using materials created by the students working on this project. Hence the project proposed here is three-fold: (i) to supply NPL with a range of well-characterised porous samples to screen materials and determine optimised properties for DAC applications, (ii) to develop new materials for DAC on the basis of feedback from (i), and (iii) scaled production of these improved materials at scale (e.g. pellets, monoliths etc.) for testing in a DAC pilot plant, together with process modelling to optimize the separation process.

在最近的研究基础上，证明了能够通过新型相互作用选择性吸附和储存CO2的新型材料的合成，该项目专注于制造旨在吸附CO2用于碳捕获应用的材料。二氧化碳的直接空气捕集（DAC）有可能成为净零经济的主要减排技术（能源白色白皮书，英国BEIS）。然而，这一领域的进展取决于设计具有理想工艺特性的新材料-例如，相对于空气的所有其他成分，对CO2的高选择性;高操作能力;高再生效率;可扩展和经济的制造。尽管对DAC系统进行了广泛的研究，但尚未找到最佳材料，这是因为先前的研究往往过于简化系统（例如，使用二元气体混合物，而空气的真实的成分要复杂得多），并且只关注过程的一部分。该项目的主要目的是开发一种材料筛选管道，该管道考虑到实际的操作条件（例如，在正确的空气成分下的多种成分的混合物，包括水，广泛的压力和温度），并涵盖所有阶段（材料合成，筛选，实验室测试和工艺设计）。此外，还需要为DAC工艺开发材料的快速筛选，主管人员正在与NPL合作开展一个项目，以设计和实施筛选潜在材料的过程;这最初将是小规模的，但是，将需要对这些材料进行大规模的验证和测试。该项目补充了Jorge博士和弗莱彻教授的iCASE奖，他们通过分子模拟（活性炭，多孔二氧化硅，RF凝胶，MOFs）为DAC筛选各种类型的多孔材料，这些材料将在NPL和Strathclyde的现实条件下使用学生创建的材料进行验证。因此，这里提出的项目有三个方面：（i）为NPL提供一系列表征良好的多孔样品，以筛选材料并确定DAC应用的优化性能，（ii）根据（i）的反馈开发DAC的新材料，以及（iii）大规模生产这些改进的材料（例如颗粒，整料等）。用于DAC中试工厂的测试，以及优化分离工艺的工艺建模。
