基于钙基载氧体燃烧分离co2还原反应动力学研究
, PP. 37-42
Keywords: 清洁燃烧,化学链燃烧,co2分离,反应动力学,caso4载氧体,未反应收缩核模型
Abstract:
根据化学链燃烧原理,进行了以caso4为载氧体,以co为燃料的化学链燃烧还原反应动力学试验研究,并基于标准gibbs自由能最小化原理,研究了以煤为燃料,caso4为载氧体化学链燃烧周期性的还原?氧化反应过程。结果表明:co还原caso4的气相产物主要为co2,固相产物主要为cas而不是cao;通过co浓度为20%~70%,温度为880~950℃条件下的还原反应验证了还原反应动力学模型,求出相关的动力学参数;试验得到的结果和拟合结果非常吻合。
