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

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