Abstract

The performance of a packed-bed adsorption column has been analyzed by numerical computations. Breakthrough curves were generated for intraparticle diffusion-controlled operation with nonlinear Langmuir equilibrium isotherms and cylindrical adsorbent particles. The resultant curves were compared with the linear-equilibrium, spherical-particle solution of Rosen. The effect of nonlinear equilibrium on the apparent diffusion coefficients was found to be significant, and a correction scheme for estimating true diffusivities was devised. It was also found that cylindrical particleshape had no effect on results for a wide range of height- todiameter ratios when the cylinder was treated as a sphere of radius equal to the hydraulic radius of the particle.
