摘要

以循环流化床(CFB)粉煤灰作为惰性载体

以Fe2O3作为活性组分

采用挤出-滚圆法制备了系列免烧Fe2O3/CFB粉煤灰载氧体颗粒

并测试了其力学性能及反应性能。研究发现

碱激发剂Ca(OH)2对CFB粉煤灰的活性效果优于NaOH

Ca(OH)2质量分数为5%时

活化效果最佳

载氧体颗粒抗压强度可以达到16.92 MPa

破碎载荷近似服从正态分布

平均破碎载荷达到53.1 N。活性组分Fe2O3与Ca(OH)2活化后的CFB粉煤灰质量比为1.5 ∶1时

载氧体颗粒抗压强度可以达到17.38 MPa

磨损率仅为0.92%

力学性能最好

且兼具良好的反应性能

综合性能最佳。CFB粉煤灰作为惰性载体的载氧体颗粒的性能与Al2O3作为惰性载体相当

验证了CFB粉煤灰作为惰性载体的可行性。

Abstract

A series of non-calcined Fe2O3/circulating fluidized bed (CFB) fly ash oxygen carrier particles were prepared by CFB fly ash as the inert support and Fe2O3 as the active component via the extrusion-spheronization method

and their mechanical and reactive properties were tested. It was found that the activation effect of Ca(OH)2 on CFB fly ash is superior to that of NaOH. When the mass fraction of Ca(OH)2 is 5%

the optimal activation effect can be achieved

with the compressive strength of the oxygen carrier particles reaching 16.92 MPa. The crushing load distribution is approximately found to follow a normal pattern

with an average crushing load of 53.1 N. When the mass ratio of Fe2O3 to Ca(OH)2-activated CFB fly ash is set at 1.5∶1

the compressive strength of the oxygen carrier particles could reach 17.38 MPa

and the wear rate is only 0.92%

indicating the best mechanical properties. Moreover

good reactivity and the best comprehensive performance are also observed. The performance of oxygen carrier particles with CFB fly ash as the inert support is found to be similar to that with Al2O3 as the inert support

verifying the feasibility of using CFB fly ash as an inert support.
