Description
CO2 capture from air using sodium hydroxide solid sorbent in a laboratory scale fluidized bed reactor was investigated experimentally. The influence of three parameters of temperature, inlet CO2 volume percentage and inlet air flow rate on the CO2 removal rate was studied. Experimental results showed that the optimum rate was at 25 oC when the inlet CO2 volume percentage was 1%. The results also showed that the adsorption process was reactive, and the reaction mechanism depended on the reaction temperature. In addition, empirical observation revealed only one adsorption cycle happened at low temperatures (25-30 oC). As the temperature increased, the second adsorption cycle occurred and, finally, CO2 desorption cycle took place in the range of 90-115 .deg. C.
