Abstract
Now a days due to rapid industrialization green house gases are continuously increasing. Carbon dioxide is the major constituent of the greenhouse gas which causes global warming and climate change. The main sources of carbon dioxide emissions are burning of fossil fuels. In our present investigation the main aim is to capture carbon dioxide (CO2) from flue gas. Adsorption is a cost effective technique to remove pollutants from flue gas. Adsorbent used here is activated carbon. In the present investigation a four stage fluidized bed reactor has been designed and operated in counter-current manner. The effect of superficial gas velocity, solid (activated carbon) flow rate, and the weir height on percentage removal of carbon dioxide (CO2) in the four stage fluidized bed reactor were investigated. The percentage removal of carbon dioxide was found to be 65 % when the flow rate of the solid is high and the flow rate of gas is low with maximum weir height of 60 mm and inlet carbon dioxide (CO2) concentration of 3000 ppm at room temperature.
