Phenomenological approach to interpret the effect of liquid flow modulation in trickle bed reactors at the particle scale
This work analyzes the influence of liquid flow modulation on the behavior of a reaction occurring in a spherical porous particle within a trickle bed reactor. A single first-order reaction between a gaseous reactant and a non-volatile liquid reactant is considered. Non-steady-state mass balances fo...
