A mass transfer heterogeneous in systems by the adsorption method

Non-linear Diffusion and Adsorption in Heterogeneous Systems by the Orthogonal Collocation Method

Non-linear diffusion and adsorption problems in heterogeneous systems are investigated in this study. Highly non-linear functions are proposed and are found necessary for the adequate representation of concentrationdependent diffusion coefficients in many practical heterogeneous diffusion and adsorption systems. The nonlinear differential equation governing the diffusion and absorption process ...

Heat and Mass Transfer Characteristics of a Zeolite 13x/cacl2 Composite Adsorbent in Adsorption Cooling Systems

The performance of the adsorption cooling system using the zeolite 13X/CaCl2 composite adsorbent was studied using a numerical simulation. The novel zeolite 13X/CaCl2 composite adsorbent with superior adsorption properties was developed in previous studies [11]. It has high equilibrium water uptake of 0.404 g/g between 25C and 100C under 870Pa. The system specific cooling power (SCP) and coeffi...

Role of Mass Transfer in Phase Transfer Catalytic Heterogeneous Reaction Systems

The Effects of a Surfactant Concentration on the Mass Transfer in a Mixer-Settler Extractor

The effects and influences of various parameters upon the efficiency and the overall volumetric mass transfer coefficients are important subjects to be studied in most liquid-liquid extraction processes. One of these important parameters is surface active agent (surfactant). In this paper, in order to study the effect of sodium dodecyl sulfate (SDS) concentration on the efficiency and the a...
