Effectiveness factor of a catalyst pellet in a trickle bed reactor. Limiting reactant in the gas phase

The influence of both internal and external wettings on the effectiveness factor of a partially wetted catalyst pellet in a trickle-bed reactor when the limiting reactant is in the gas phase is analyzed. A new parameter, not considered up to now, measuring the gas-liquid interfacial area inside and...
