홈페이지논문 초록 (Abstract)
Reduction characteristics of oxygen carrier particle for different gaseous fuels such as methane, syngas and LPG were measured in a bubbling fluidized bed reactor. For all gaseous fuels, high CO2 selectivity was achieved at high temperature more than 800 °C. Moreover, CO2 selectivity decreased as the temperature decreased and as the fuel flow rate increased because limitation of oxygen supply from the oxygen carrier. However, CO2 selectivity increased as the solid height in the reactor increased due to the increment of oxygen supply from more oxygen carrier and the increment of gas residence time in the reactor. Consequently, we could conclude that the high reaction temperature, low gas velocity, and high oxygen carrier inventory are preferable to ensure high reactivity of oxygen carrier in the fuel reactor.
