Bubbleless Fluidization Studies in China

In November 1975, a chance meeting in Tokyo brought Mooson Kwauk and me together for the first time in nearly two decades. I found in Kwauk another enthusiast for fluidization at high velocity—indeed, an enthusiast 

Kwauk s Institute of Chemical Metallurgy has conducted research on each of the bubbleless fluidization alternatives. 

In the 1950s, a major effort had been devoted to systems of dilute raining particles, offering advantages of high gas-particle heat and mass transfer, low pressure drop, and low cost of chimney-like equipment. The systems have been exploited on the pilot or demonstration-plant scale  

During a visit to the Institute of Chemical Metallurgy in June 1979,1 was astonished by the range, sophistication, and aptness of high-velocity fluidization research in progress there, only five years after the Institute had been reinstated with Kwauk as its director. Already, the work had cast 

The Institute s primary interests, however, were the fast-bed boiler and the fluid catalytic cracker regenerator.
