Coherent and incoherent frontal patterns for multicomponent adsorption dynamics—II. Non-uniqueness of frontal patterns in the isothermal case for convex isotherms of two-component mixtures

Abstract

Abstract It has been shown that of frontal patterns can be non-unique in the isothermal case for convex adsorption isotherms of two-component mixtures with variable coefficients of separation. The uniqueness of frontal patterns have been analysed by using extreme conditions. The influence of the dispersive factors on the nature of the concentration distribution is considered. It has shown that the dispersive factors can qualitatively change the nature of concentration distribution in the adsorber too: (a) convert coherent patterns into incoherent ones; (b) transform some coherent patterns into other coherent ones.
