The adsorption rates and equilibrium constants are important parameters in the a priori design of activated-carbon beds employed to separate carbon dioxide, sulfur dioxide, and hydrogen sulfide from air and combustion gases. In particular, intraparticle diffusivities in the macro- and micropore regions and the adsorption equilibrium constant are parameters that laboratory studies must establish. The University of California reported the parameters for CO/sub 2/ in 1979. The values of the parameters for adsorption of hydrogen sulfide and sulfur dioxide on the common types of activated carbon indicate that intraparticle transport strongly affects the overall adsorption rate. Consequently, particle size and pore-volume distribution information are prerequisites for the careful design of activated-carbon beds for these gases.
