Assessment of mass transfer in the stagnant liquid regions in trickle-bed reactors
A critical revision has been carried out of experimental investigations to quantify the size of the liquid stagnant region in fixed beds with co-current gas-liquid down-flow, and its ability to exchange mass with the dynamic region and with the particle surface. The revision has exposed that a high...
