Investigation of the Performance of Low-Cost Calcium-Based Oxygen Carrier in Chemical Looping Combustion of Coal
摘要
Abstract
Chemical-looping combustion(CLC) will be a very promising technology due to its high efficiency and low-cost for CO2 separation.In this paper,the reduction/oxidation characteristic as well as the cyclic performance of low-cost calcium-based oxygen carrier was investigated in a bench-scale fixed-bed reactor.The effect of temperature,operating pressure and coal/oxygen carrier mass ratio on the performance of calcium-based oxygen carrier were discussed.The results showed that increasing temperature and pressure can obviously enhance the reaction of calcium-based oxygen carrier with coal gasification products,which can lead to higher CO2 yield and carbon conversion.Such factors as the parallel reactions and the resistance of internal mass transfer in the oxygen carrier particles in practical reaction lead to inactivation of the oxygen carrier and the decrease of the oxygen carring ability.The coal/oxygen carrier mass ratio should be limited to 0.14 to get higher CO2 yield and carbon conversion.关键词
