About this collection
Reactive Capture of CO2 (RCC) refers to a process integration where conversion of CO2 into a value-added product can be achieved directly from a sorbent which captures CO2. In some cases, it can be a solid sorbent working in concert with a catalyst or it can be a solution-phase sorbent which also serves as reaction medium for catalysis. In either scenario it has been estimated that RCC could provide 40% in energy savings relative to traditional CO2 capture and release since there is no need for thermal energy to be used to release CO2 before it is converted into fuel or chemical. It has been predicted that the products derived from RCC could be used to offset the costs of carbon capture when employed for industrial systems. Catalysis can be driven thermally or via an electrochemical system. It is well-known that CO2 sorbent mixtures are comprised of many equilibria, and therefore the substrate for RCC has the potential to be a variety of molecules and this leads to a potentially rich chemistry for CO2 conversion. As examples, RCC may have as substrate the CO2:sorbent adduct, or the substrate may be CO2 that is release from equilibria in the solid or solution phase sorbent.
