Institute of Process Engineering (IPE), Chinese Academy of Sciences (CAS) has undergone for 60 years since its foundation in 1958. This institute upholds the policies of Chinese Academy of Sciences, turns herself always to be in the directions of scientific frontline, great requirements of country and major fronts of national economy, and by far has acquired a series of important achievements in applied basic researches and industrial applications, especially in fluidization sciences and technologies. Under the direction of the earlier institute director Kwauk Mooson, IPE has constantly been in the internationally leading position in the area of fluidization science and technology. This paper briefly reviews a series of important achievements on fluidization theory and application at IPE. They are, for example, the generalized fluidization, idealized bubbleless fluidization, paticulatization of gas solids fluidization, relationship between structure and transfer in fluidized bed, energy-minimization multi-scale method, and micro fluidized bed characterization and definition in theory respect, and fluidized roasting of Chinese iron ores, fluidized bed pyrolysis of coal, fluidized reduction of Chinese manganese ores, low-NOx dual fluidized bed decoupling combustion of N-rich fuels, low-tar two-stage fluidization gasification, and computational simulation scale-up of MIP circulating fluidized bed reactor in dustrial application respect. This paper presents as a gift to the 60th anniversary of the IPE’s foundation, in order to impel us to inherit and to develop the truthful, pragmatic, patriotic, dedicated spirit of older scientists, and to make greater achievements in scientific research.
