The project is mainly experimental in nature. Sieved samples of a variety of UK, Canadian and Spanish limestones will be pre-calcined and sintered at elevated temperatures to differing extents under various steam atmospheres, potentially with the addition of salts. The relativities of the produced materials will be tested, initially in a thermogravimetric analyser and subsequently in a small electrically-heated fluidised bed. If time allows, extended work will be conducted at elevated pressure (10 - 20 bar), more typical of conditions in pre-combustion capture. In essence, the aim of the project is to develop inexpensive sorbents for CO2 to work within an efficient thermodynamic cycle. Grant number: UKCCSRC-C2-206.
