Development of calcium-based, copper-functionalised CO2 sorbents to integrate chemical looping combustion into calcium looping

We experimentally demonstrate the feasibility of a novel process that integrates chemical looping combustion into the calcium looping scheme. Using a co-precipitation technique, calcium-based, copper-functionalised CO2 sorbents were developed. The material synthesized possessed stable CO2 uptake and oxygen carrying capacities, making it an attractive candidate for the modified calcium looping process.
