Significant radial profiles of concentration and temperature may exist in packed bed adsorbers, leading to a different breakthrough behavior at the wall than in the core of the bed. Respective data have been gained by near-infrared tomography for zeolite and water in relatively narrow tubes, and are

The effect of velocity changes in fixed-bed adsorption of ternary mixtures (two absorbable components and one inert) is analyzed. In a diluted system governed by linear isotherms transition types are contact discontinuities. It is shown that the velocity variations (nontrace systems) resulting from
