Abstract Chemical-looping with oxygen uncoupling (CLOU) is one of the emergent fuel combustion technologies being currently investigated which has the potential to assist with CO2 capture from coal-fired power plants. CLOU involves the combustion of fuel in the presence of gaseous-phase oxygen released from the decomposition of an "oxygen carrier" (OC) metal oxide (e.g. CuO). Compared to Chemical-looping Combustion (CLC), the CLOU process has the promise of reducing the fuel reactor volume and the OC inventory.. The CLC process requires slower pre-gasification reaction of the solid fuel into synthesis gas, which is eventually oxidized by the circulating oxygen carrier. The presentation discusses components of the program at the University of Utah including laboratory-scale fluidized bed experiments, process modelling, and construction of a new 100-200 kW process development unit (PDU). The goal of the laboratory-scale experiments is to derive kinetics for the reduction and oxidation of the OCs. The process model is being used to explore material and energy balance scenarios. These scenarios are looking at the amount of OC circulated and, given the kinetics, OC inventories needed. The process model also shows potential heat recovery. Finally, the PDU design considerations are discussed and updates on the construction given.
