流化床用微球催化剂磨损研究

Study on attrition of fluidized bed microsphere catalyst

介绍了流化床催化剂颗粒磨损类型、磨损测试及磨损机理模型分析三方面的研究进展;综述了催化剂颗粒磨损的时变规律及各因素对其磨损的影响,指出今后应加强对热力磨损、化学磨损、微观磨损机理的研究,建立更加完善的动力学模型,为流化床技术改进提供指导。

The research advances of microsphere particle attrition type,attrition test method and attrition mechanism model are introduced;the time-varying law of catalyst particle attrition and the influence of various factors on catalyst attrition are summarized.It is suggested that the research on thermal attrition,chemical attrition and attrition mechanism should be continued and developed,and a more perfect kinetic model should be established to improve the fluidization technology.
