Triphase catalysis: mass transfer and kinetic studies
2018The importance of phase transfer catalysis (PTC) in the production of high value chemicals has grown immensely over the past few years. PTC may be a suitable method to synthesize a product whenever each reactant is miscible in a different phase. By addition of a PT catalyst, which functions as a ferrying agent between the phases, significant rate ...

Balances, Kinetics of Heat and Mass Transfer
2011Process engineering attends to yield products with a set of desired properties, given some raw materials. This aim may be achieved through several different process variants, which are found by process design. They usually differ with respect to feasibility, safety and particularly to cost effectiveness.

Mass Transfer and Kinetics of Ion Exchange
1983These papers were written by leading scientists and technologists working in the field of ion exchange, and they discuss the synthesis, equilibria, transport phenomena, kinetics and design of ion exchange resins and membranes, both systematically and progressively.

The Stability and Kinetics of Peritoneal Mass Transfer
1989Adequacy of peritoneal dialysis is dependent upon optimal solute and water transfer from the capillaries to peritoneal dialysate within the peritoneal cavity. Mass transfer is governed by the permeability of the capillary wall, the peritoneal interstitium and the mesothelial layer.

Kinetics of Mass Transfer-Limited Bacterial Growth on Solid PAHs
Environmental Science & Technology, 2000The importance of mass transfer relative to the intrinsic microbial activity was examined in a laboratory system using Mycobacterium sp. LB501T and poorly soluble anthracene as sole carbon source. M. sp. LB501T was grown on various amounts of solid anthracene in batch cultures, and microbial biomass formation was compared to independently determined ...

Study of the mass transfer kinetics in a monolithic column
Journal of Chromatography A, 2003The purpose of this work is to investigate the mass transfer kinetics of butylbenzoate on a monolithic RPLC column, with methanol-water (65:35, v/v) as the mobile phase. We used the perturbation method, measuring the height equivalent to a theoretical plate (HETP) of the peaks obtained as the response to small pulses of solute injected on a ...

International Journal of Heat and Mass Transfer, 1998
Abstract The theoretical analysis about the influence of high concentration and large concentration gradients on the hydrodynamics and mass transfer in the approximations of the laminar boundary layer has been done. The results obtained show that the change in the density with the concentration influences the hydrodynamics in gases and liquids and ...

Mass transfer kinetics of adsorption on suspended solid particles
Journal of Colloid and Interface Science, 1978A theoretical kinetic model for adsorption from an agitated liquid phase to solid spherical particles suspended therein has been formulated, solved numerically and compared with the results of experiment. Important aspects of the model include the fact that it accounts for the influence of forced convection as well as the influence of adsorbate ...

Phase and area contributions to mass transfer kinetics
AIChE Journal, 1961AbstractA relationship has been developed describing quantitatively the factors affecting packed column performance. The relationship, based on the Colburn equation, is proposed within the limits of a consistent flow regime in the liquid phase.Via separation of the effects of packing geometry on diffusion rates and the effect of area variation with ...
