This is a PhD research project in chemical engineering. The direct capture of CO2 from the atmosphere is a technology that willbecome essential to combat climate change. This can be done using either liquid solvents orsolid adsorbents, where the solid adsorbents seem to present a number of advantagescompared to solvents. The solid sorbent materials used for direct air capture of CO2 aremostly reactive materials, such as amine enhanced silica or alumina. There are currently ahandful of start-up companies worldwide, who pioneer direct air capture with the use ofsolid, chemical adsorbents.Standard adsorption-desorption cycles for direct air capture have been developed and arecommercialised, but the investigation of direct air capture processes is just in its infancy.This implies that there is much room to develop more efficient or fit-for-purpose adsorptionprocesses. An established way to do this is through mathematical modelling and simulation.During the PhD, the candidate will develop these models and will use them to investigateinnovative cycles, which may lead to better performance in terms of energy consumptionand costs.

这是一个化学工程方面的博士研究项目。直接从大气中捕获二氧化碳的技术将成为应对气候变化的关键技术。这可以用液体溶剂或固体吸附剂来完成，固体吸附剂似乎比溶剂有许多优点。用于直接捕集二氧化碳的固体吸附材料大多是反应性材料，如胺增强的二氧化硅或氧化铝。目前世界上有几家初创公司，他们利用固体化学吸附剂开创了直接空气捕获的先河。直接空气捕获的标准吸附-解吸循环已经开发出来并已商业化，但直接空气捕获过程的研究才刚刚起步。这意味着有很大的空间来开发更高效或适合用途的吸附过程。一种既定的方法是通过数学建模和模拟。在博士学位期间，候选人将开发这些模型，并使用它们来研究创新周期，这可能会在能源消耗和成本方面带来更好的性能。
