Abstract
The problem of CO₂ mitigation on a small and medium scale can be resolved by developing a combined system of CO₂ capture and its consecutive conversion into valuable products. The first stage of CO₂ looping, however, should be reliable, effective and easy to control and radiofrequency heating, as a new advanced technology, can be used to improve the process. CO₂ absorption and desorption RF units can be installed within power plants and powered during the periods of low energy demand thus stabilizing the electrical grid. In this work, a CaO sorbent produced by template synthesis was studied as a sorbent for a CO₂ looping system under RF heating which offers short start-up times, highly controlled operation, high degree of robustness and low price. The sorbent reached its stable CO₂ capacity of 15.4 wt.% already after 10 temperature cycles (650/850 °C) under RF heating. Higher CO₂ desorption rate and lower degree of the sorbent sintering was observed under RF heating as compared to conventional heating
