Abstract
Expressions are given for the concentration of a dilute reactive gas mixed with an inert carrier gas as a function of the radial and longitudinal distances in a cylindrical reactor and the reaction efficiency. The reaction efficiency is defined as the fraction of gas-wall collisions that leads to the disappearance of the reactive gas from the gas phase. The solutions presented here are applicable for all values of reaction efficiencies and extend earlier work by other investigators that was applicable only for values of 1 or near zero. In addition to the solution of Fick's second law of diffusion as applied here (with an additional term for flow in the cylinder), a one-dimensional random walk analysis is also applied to this problem. The combination of diffusion equation solutions and the random walk analysis leads to the conclusion that, for a given set of experimental conditions, the reaction efficiency can be uniquely determined only if it lies within a certain range of values. Small values of the reaction efficiency will produce insufficient reaction and large values will yield diffusion-limited results.
