Methods are developed for predicting the performance of different types of three‐phase reactors for removal of a gaseous reactant by catalytic reaction. The removal is assumed to occur by mass transport of reactant from gas‐to‐liquid and liquid‐to‐catalyst particle and then by intraparticle diffusion and reaction in the liquid filled pores. The method is applied to the oxidation of sulfur dioxide at 25°C and 1 atm using activated carbon, in the presence of water, as a catalyst. Slurry, trickle‐bed, and counterflow packed‐bed reactors are compared in terms of the key variables affecting the fraction of sulfur dioxide reacted.
