Abstract
Ca-looping is a potentially effective method for CO2 capture from coal fired power plants. In this work, using a custom made tube furnace experimental system that can measure sample weight changes at constant temperatures, water vapor effect on calcination and carbonation of calcium based CO2 sorbent are studied. The effects of steam present in calcination and carbonation process is determined. It is found that steam has a positive overall effect on CO2 capture in the Ca-looping process. When present in both calcination and carbonation processes, steam can increase the decomposition rate of the CaCO3 and enhance the subsequent carbonation conversion of the calcined CaO.
