摘　　要：首先追溯了催化裂化工艺的起源,简略回顾其起步于固定床工艺,经历短暂的移动床,再到流化床,终至循环流化床工艺的历程。随后,聚焦快速床研究,特别是国内科研人员在此领域的系统性研究工作。在理论模型的发展过程中,中国科学院过程工程研究所与中国石油化工集团公司等单位紧密合作,共同推动了催化裂化工艺技术的多次重大升级和迭代,包括催化裂化快速床再生器技术和最大化异构烷烃变径流化床反应器技术等。随着中国催化裂化技术的持续进步,国内的快速床研究也在不断深化,研究范围从试验观察扩展到轴向模型、多尺度理论再到多尺度模拟方法。通过梳理快速床研究的发展脉络及其与催化裂化工艺的紧密联系,旨在为新技术和新理论的研究提供启示和思路,以期推动流态化技术在未来的发展和应用。This paper begins by tracing the origins of catalytic cracking processes,briefly reviewing their evolution from the initial fixed-bed operations,through a short phase of moving-bed processes,to the development of fluidized bed technologies,and ultimately to the circulation fluidized bed processes.Subsequently,the focus is on the rise of research in fast fluidized beds,particularly the systematic research efforts in this field by domestic scientists represented by Mooson Kwauk.During the development of theoretical models,the Institute of Process Engineering,Chinese Academy of Sciences,worked closely with SINOPEC and other entities to jointly promote several significant upgrades of catalytic cracking process technologies,including the technology for fast fluidized bed regenerators and the technology for maximizing the production of isomerized alkanes in diameter-transformed fluidized bed reactors.With the continuous advancement of catalytic cracking technology in China,domestic research on fast fluidized beds is also deepening,with the scope of research expanding from experimental observations to axial models,multi-scale theories,and multi-scale simulation methods.By reviewing the development trajectory of fast fluidized bed research and its close relationship with catalytic cracking processes,this paper aims to provide insights and ideas for the study of new technologies and theories,in the hope of promoting the future development and application of fluidization technologies.
