摘要: Abstract The fluidization characteristics of binary mixtures containing tobacco stem (TS) and cation exchange resin (a substitute for coal) were studied in a rectangular bed with the cross-section area 0.3 × 0.025 m 2 . presence herbaceous biomass particles their unique properties such as low density high aspect ratio resulted different behaviors. Three velocities, i.e. initial, minimum full observed TS mass fraction increased from 7% to 20%, four hydrodynamic stages experienced, including static, segregation, transition mixing stages, increasing operational gas velocities. results suggest that velocity should be range 2.0–5.0 times mixtures, less than used an existing bubbling fluidized bed. Higher inclusion requires introduction central jet improve effect.
