The behaviour of a commercial sorbent for CO2 capture in a dual interconnected fluidised bed looping process under simulated sorption-enhanced gasification conditions was investigated in a lab-scale apparatus. Each test consisted of ten calcination/carbonation cycles plus an eleventh calcination stage. Calcination was carried out at 850°C in 10% CO2. Carbonation was carried out under six different test conditions, by varying temperature (600-700°C) and in absence/presence of 10% steam. CO2 concentration was set at 10% as well. CO2 capture capacity, elutriation rate and sorbent particle size distribution were obtained, and the results were discussed as a function of the operating parameters.

Abstract
The behaviour of a commercial sorbent for CO2 capture in a dual interconnected fluidised bed looping process under simulated sorption-enhanced gasification conditions was investigated in a lab-scale apparatus. Each test consisted of ten calcination/carbonation cycles plus an eleventh calcination stage. Calcination was carried out at 850°C in 10% CO2. Carbonation was carried out under six different test conditions, by varying temperature (600-700°C) and in absence/presence of 10% steam. CO2 concentration was set at 10% as well. CO2 capture capacity, elutriation rate and sorbent particle size distribution were obtained, and the results were discussed as a function of the operating parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
