Irreversible Chemical Reaction

An expression has been derived for the concentration of oxidant and reductant at the surface of an expanding spherical electrode as a function of time and the polarizing potential in the case where a slow irreversible chemical reaction follows a reversible electron transfer reaction under the conditions of a somewhat idealized polarographic system.

Irreversible Chemical Reaction

This paper presents a particle method for free turbulent reacting flows. The vorticity and concentration fields are discretized into the vortex and concentration elements, respectively, and the behavior of the elements is calculated with the Lagrangian method. The chemical reaction is estimated through the Lagrangian calculation for the strength of concentration element. The particle method is applied to simulate a plane mixing layer with a single-step and irreversible chemical reaction of non-premixed reactants so as to discuss the applicability.

A model of particle growth kinetics in a condensing system is investigated in which the mechanism is presumed to be an irreversible chemical reaction which proceeds at the particle-atm osphere interface. General growth laws for the assembly of particles are derived from the resulting infinite set of differential equations and tested against growth data on sulphur hydrosols. The relation between the model and the well-known pure birth process of mathematical statistics is emphasized.

Irreversible Chemical Reaction

In this study, the mass transfer accompanied by an instantaneous irreversible chemical reaction in a slurry bubble column containing sparingly soluble fine reactant particles has been analyzed theoretically. Based on the penetration theory, combining the cell model, a one-dimensional mass transfer model was developed. In the model, the effects of the particle size and the particle dissolution near the gas-liquid interface on the mass transfer were taken into account. The mass transfer model was solved and an analytical expression of the time-mean mass transfer coefficient was attained. The reactive absorption of SO2from gas mixtures into Mg(OH)2/water slurry was investigated experimentally in a bubble column reactor to validate the mass transfer model. The results indicate that the present model has good predicting performance and could be used to predict mass transfer coefficient for the complicated gas-liquid-solid three-phase system with an instantaneous irreversible chemical reaction.
