Mathematical Modeling of Fluorination Reaction of Uranium Dioxide and Evaluation of Existing Gas-Solid Reaction Models

Singlet delta oxygen production from a gas-solid reaction.

Spontaneous reactions between alkali metal or alkaline earth peroxides and hydrogen (deuterium) halide gases demonstrate the efficient production of singlet delta oxygen in a non-liquid medium. These reactions occur under ambient conditions without the need for any external energy source. The production of singlet delta oxygen was verified by direct emission spectroscopy at 1.27 microns with a ...

Travelling Waves for Solid-gas Reaction-diffusion Systems

We study a two-species reaction-diffusion problem described by a system consisting of a semilinear parabolic equation and a first order ordinary differential equation, endowed with suitable conditions. We prove the existing of a unique traveling wave profile and give necessary conditions and sufficient conditions for the occurrence of penetration and conversion fronts.

Gas-Solid Interaction

The heats of adsorption on weakly activated ^-aluminium oxide for a number of linear alkanes (from n-butane to n-nonane) and for 2.2.4-trimethylpentane have been determined by GSC and extrapolated to zero surface coverage. The dependance of the adsorption energy on the number of carbon atoms is discussed on the basis of the bidimensional gas model: it is shown that the interactions of the adsor...

Gas-Solid Catalytic Reactions

The outline of this chapter is as follows: *.1 will show some application areas together with the number of types of reactors available for carrying out gas-solid catalyzed reactions. Section *.2 will focus on the kinetic models suitable for describing these reactions. Section *.3 will show how to set up the reactor models and will also show the mass transport interactions need to be modeled. T...
