This work proposes a new strategy for the scaling of bubbling fluidized
bed reactors. This strategy is based on the bubble size distribution,
bubble coalescence phenomenon, and the chemical reactivity, allowing to
deduct the dimensionless number Chejne-Macias-Maya that must remain
constant at different scales to guarantee the fluidization regime. The
proposed strategy is validated from computational simulations carried
out at different operating conditions. Additionally, limits for the
validity of this scaling strategy were determined, which agrees with
those reported in the literature.
