UKCCSRC Call 1 Project: Chemical looping for low-cost oxygen production and other applications

While chemical looping (combustion, CLC) is a promising technology for carbon capture, however many questions still remain as to its applicability at an industrial scale. In Chemical looping combustion a metal oxide is shuttled back and forth between a fuel and air reactor, picking up oxygen in the air reactor and transferring it to the fuel reactor. The fuel is never mixed with the nitrogen from the air, so a stream of CO2 and H2O is produced directly from the fuel reactor; this potentially makes the integrated power production and CO2 capture system highly efficient. Most CLC and CLOU schemes envisage using fluidised beds in which the solid fuel is intimately mixed with the oxygen carrier, or mixing of the solid fuel particles. This project aims to push forward chemical looping within the UK and integrates both experimental work and theoretical analysis to result in the first large-scale demonstration of CLC within the UK.

化学循环燃烧（燃烧型化学循环，CLC）作为一种具有潜力的碳捕集技术，尽管如此，其在工业规模应用方面仍存在诸多疑问。在化学循环燃烧过程中，一种金属氧化物在燃料反应器和空气反应器之间往返穿梭，从空气反应器中吸收氧气并将其转移至燃料反应器。燃料从未与来自空气的氮气混合，因此，燃料反应器直接产生二氧化碳和水蒸气流；这有可能使得集成电力生产和二氧化碳捕集系统具有极高的效率。大多数CLC和CLOU方案设想使用流化床，其中固体燃料与氧气载体紧密混合，或固体燃料颗粒的混合。本项目的目标是推动英国化学循环技术的发展，并将实验工作和理论分析相结合，以在英国实现CLC的首个大规模示范。项目资助编号：UKCCSRC-C1-39。
