Comparative study of the batch adsorption kinetics and mass transfer in phenol-sand and phenol-clay adsorption systems

Particulate Science and Technology, 2019
This study was aimed at evaluating the kinetics and mass transfer of phenol adsorption onto sand and clay sediments. The adsorption studies were carried out in batch mode.

Mass transfer under interfacial turbulence: kinetic regulaties

Chemical Engineering Science, 1992
Abstract A semiempirical model of mass transfer accompanied by interfacial turbulence is proposed which accounts for the linear dependence of the mass transfer coefficients on the driving force under interfacial turbulence conditions. Power correlations are also discussed in the framework of the model, and it is shown that different types of ...

Effect of mass transfer and kinetics in ordered Cu-mesostructures for electrochemical CO2 reduction

Applied Catalysis B: Environmental, 2018
Mass transfer, kinetics, and mechanism of electrochemical CO2 reduction have been explored on a model mesostructure of highly-ordered copper inverse opal (Cu-IO), which was fabricated by Cu electrodeposition in a hexagonally-closed packed polystyrene ...

Mass Transfer Kinetics of Osmotic Dehydration of Pineapple

Journal of Food Processing & Technology, 2017
Current study deals with the kinetics and mathematical modelling of osmotic dehydration of pineapple. Pineapple (Ananas comosus), 10 mm thick slices weighing 50 g each, was studied for the osmotic dehydration using hypertonic solutions of sucrose and fructose.

Kinetics of Aerosol Mass Transfer

2011
It has been demonstrated that a small change in the power of the trapping laser beam can be used to induce a small change in droplet absorption. This gives rise to a small shift in the droplet temperature and hence in the equilibrium size at a given relative humidity.

Mass transfer and growth kinetics in filamentous fungi

Chemical Engineering Science, 1997
A mechanistic model has been developed to describe mass transfer and growth kinetics in filamentous fungi on solid substrate before branching takes place. The model accounts for substrate diffusion in the solid medium, uptake and release of substrate at the fungal wall membrane by a carrier, and formation of wall precursors coupled to mass transport by

Mass-transfer kinetics in dissolving polydisperse solid materials

International Journal of Heat and Mass Transfer, 1976
Abstract A theoretical model for the dissolution of polydisperse mixtures of solid particles in mechanically agitated liquids has been developed. Results of the theoretical analysis are presented in terms of expressions in which the mass of the solid solute time rate of mass transfer and the particle size distribution explicitly depend on time.

Heterogeneous mass-transfer kinetics under diffusion-controlled conditions

Journal of Engineering Physics, 1989
Calculations have been performed on nonisothermal mass transfer with transport characteristics dependent on temperature: velocity, concentration, temperature, and mass-transfer coefficient distributions.

MASS TRANSFER KINETICS of OSMOTIC DEHYDRATION of MUSHROOMS

Journal of Food Processing and Preservation, 1992
A continuously circulated contacting reactor was designed and used for the osmotic process. Mushrooms were treated in two ways: (1) Sliced mushrooms were blanched and osmotically processed in 5, 10 and 15% salt solutions for 5, 10, 20 and 30 min at room temperature (called type 1 mushrooms); (2) Sliced and blanched mushrooms were osmotically dehydrated
