Looping Reactor Configurations for CO2 valorization

Chemical Looping reactor configurations, especially in the context of coal combustion offer merits in terms of oxygen supply without direct contact of fuel with air. Metal oxides that serve as oxygen carriers are looped between two reactors, during which they separately deliver oxygen to the fuel and then pick up oxygen from the air stream. This leads to fuel combustion and the resultant energy generation, while also producing a nearly pure stream of CO2 suitable for sequestration and creating opportunities for CO2 valorization.  Research in my group has focused on developing advanced configurations for polygeneration (i.e. power generation as well as chemicals production) using such reactor configurations.
