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/sup 0/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.
