“…For benzene and carbon particles, the process at the site is one of physical adsorption for which the intrinsic rate is very high. This has been confirmed by many studies in gaseous systems, for example, by Shen and Smith (1968) for benzene adsorption on silica gel. They found that equilibrium could be assumed between concentrations in the fluid and on the surface.…”

Experimental rates have been measured at 24°C for the solution of benzene from gas bubbles into water and aqueous slurries of activated carbon particles. Batch-type experiments were carried out so that the data at low time values gave from a single-resistance equation the mass transfer coefficient ki from gasbubble interface to bulk liquid. For bubbles whose diameter was 1.8 mm kt was about 4 X 10-2 cm/sec.The same value was obtained for the solution of benzene in water alone or in aqueous slurries of carbon particles. Rate data were measured for various concentrations of carbon particles in the slurry. Although it was not possible to achieve conditions where mass transfer to the particle surface controlled the rate, data were obtained at bubble-to-particle area ratios as high as 1.7-2.7. Interpretation of these results in terms

This work was carried out in the laboratory of Prof. M. Kahlweit. I am indebted to him and to Dr. R. Strey for suggestion of the problem and advice with the experiments. I am further indebted to D. Luckmann for drawing the figures.

“…The constitutive relation ( 2) is usually called the equation of isothermic sorption and is, in general, a complicated nonlinear function of U in which mutual influences among different solutes are taken into account. Since the ideal localized monolayer model was introduced by Langmuir [25], the Langmuir relation has been extensively employed also for multiple solutes, and its experimental evidence has been presented [13,36]. In this case, the relations (2) can be expressed as follows…”

“…Hence, it is of interest to analyze the effect of the interaction process on the breakdown of the solution or, in other words, on the distortion of the wave profile. Actually, by means of the relations ( 28)- (30) and making use of (12), in regions I, II and III, respectively, the critical distances x k (36) with (38) yields the following restriction upon the column length…”

Nonlinear wave interaction processes for a quasilinear hyperbolic homogeneous system of first-order partial differential equations multicomponent chromatography are investigated. The wave analysis is worked out by extending to the present multicomponent case the leading ideas of a well-established method of approach that was developed for solving initial value-wave problems in terms of exact solutions to 2 × 2 hyperbolic homogeneous systems. These interaction processes may model different situations concerning the separation of a mixture into its chemical components. Several numerical plots are also given in order to illustrate the behavior of the exact wave solutions arising from the analysis that is accomplished.
