Periodic operation of trickle bed reactors: An approach to catalyst design through modeling at the particle scale
The behavior of an isothermal catalytic particle in a TBR with ON-OFF liquid flow modulation has been modeled considering isothermal conditions. The impact of catalytic properties has been investigated considering uniform and egg shell distributions. Furthermore, the effect of varying inert core por...
