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.
