摘　　要：The bed expansion in the dense region of FCC turbulent fluidized bed has been studied in a cold fluidized bed made of plexiglass with 710×4000/870×ll000mm and a RFCC regenerator(800,000T／a）.By using dimensional analysis,a calculation equation of dense phase density correlated by dimensionless groups is obtained.The equation may be use ful for process engineering design of commercial units.The bed expansion in the dense region of FCC turbulent fluidized bed has been studied in a cold fluidized bed made of plexiglass with 710×4000/870×ll000mm and a RFCC regenerator(800,000T／a）.By using dimensional analysis,a calculation equation of dense phase density correlated by dimensionless groups is obtained.The equation may be use ful for process engineering design of commercial units.
