Process modelling and techno-economic analysis of natural gas combined cycle integrated with calcium looping [PDF]
, 2016 Calcium looping (CaL) is promising for large-scale CO2 capture in the power generation and industrial sectors due to the cheap sorbent used and the relatively low energy penalties achieved with this process. Because of the high operating temperatures the

Using chemical-looping with oxygen uncoupling (CLOU) for combustion of six different solid fuels [PDF]
, 2008 Chemical-looping with oxygen uncoupling (CLOU) is a novel method to burn solid fuels in gas-phase oxygen without the need for an energy intensive air separation unit. This paper presents batch laboratory fluidized bed CLOU tests where six different solid
