摘要: Abstract The effect of fines on the hydrodynamics a gas–solid fluidized bed and ozone decomposition reaction was investigated using high-density iron-silicon (FeSi) particles with particle density 6690 kg/m3. addition decreased bubble size, dense phase voidage reactor performance. size decrease is in accordance reported literature; while, increase performance found literature less catalyst. quantified an apparent overall mass transfer parameter derived from fitting two-phase model to experimental data. method allowed for comparison despite fluctuation FeSi activity. Model results suggest that smaller bubbles should improve However, counteracted effects bubbles. Higher entrainment rate noted.
