摘要:
化学链燃烧技术逐渐发展成为一项非常有前景的实现CO2高效低能耗分离捕集技术.在小型固定床上研究了廉价钙基载氧体的还原/氧化反应特性以及持续循环能力,讨论了温度、压力、煤/载氧体质量比对钙基载氧体反应特性的影响.试验结果表明,温度和压力的升高能显著增强煤气化产物与CaSO4之间的反应,导致CO2收率和碳转化率相应增加.在煤/载氧体高质量比情况下,由于实际反应过程中存在平行反应、载氧体颗粒内部传质阻力等因素,造成载氧体的失活和载氧能力下降.故为得到高的CO2收率和碳转化率,煤/载氧体质量比应控制在0.14以下.
Abstract:
Chemical-looping combustion ( CLC) will be a very promising technology due to its high efficiency and lowcost for CO2 separation． In this paper，the reduction /oxidation characteristic as well as the cyclic performance of lowcost 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．
