In this study, the carbon dioxide sorption using solid sorbent (sodium carbonate supported on alumina) in fixed and fluidized bed reactors was investigated. The key objective was to examine the carbon dioxide concentration profile or breakthrough curve (as well as capture capacity) and carbon dioxide sorption kinetic parameters with various flow regimes/flow patterns. The basic information for the sorption kinetic parameter computation was the breakthrough curve under different flow operating conditions. From the results, all the breakthrough curves were constant at the beginning stage then it decreased with the sorption time. The fixed bed gave longest sorption time. All the carbon dioxide gas was not captured in the fast fluidization flow regime. The turbulent fluidization flow regime exhibited highest carbon dioxide capture capacity. In addition, the employed deactivation kinetic model fitted well with the obtained experimental information. The initial sorption and deactivation reaction rate constants were the highest at the turbulent fluidization flow regime. Â
