Scale-up of bubbling fluidized bed reactors with vertical internals: A new approach accounting for chemistry and hydrodynamics

摘要

The full set of scaling law derived by Glicksman allows the hydrodynamic scale-up of fluidized bed reactors. In case of catalytic reactors, changing the catalyst particle diameter during scale-up may have consequences for the catalyst activity, selectivity and deactivation behavior. For fluidized bed reactors with vertical internals, a new scale-up approach is proposed and tested that helps to avoid this dilemma.
