A novel concept of looping combustion of carbon (CarboLoop) is presented. It is based on the feature of carbons to extensively uptake oxygen upon exposure to air at moderate temperatures. Surface oxides of carbon are eventually released as combustion products (CO, CO2,) as the oxidized fuel is brought to moderate-to-high temperature in an oxygen-free atmosphere. This concept is pursued to the formulation of a preliminary scheme of a looping combustor of carbons based on a dual interconnected bed reactor system. One of the reactors is air-blown and acts as the fuel oxidizer. The second reactor, operated with partial recycle of gaseous effluents (CO2,+ impurities), acts as the fuel desorber. Operating conditions of the oxidation and desorption stages may be properly tuned, leading to alternative looping strategies. The present study lays down the basic mechanistic background for analyzing the process, based on a simplified semiglobal approach to combustion and oxidation of solid carbons. The soundness of the CarboLoop concept has been verified by purposely designed experiments. The alternated oxidation/desorption stages typical of a looping combustor are simulated in a thermogravimetric analyzer. Experiments were directed to monitoring the oxidation and desorption steps under simulated looping conditions. Graphitized coke has been used as a surrogate carbon fuel. The experimental results confirm the soundness and potential of the CarboLoop concept and lay the path for its further development.
