Abstract
This paper describes a mathematical model for a single catalyst particle in which several chemical reactions take place. The model includes transport restrictions against mass and heat transfer in the interior and in the gas film surrounding the particle, and it accepts a general type reaction rate expression such as a power law expression or a Langmuir-Hinshelwood expression. The model is reduced to a number of coupled second order differential equations — one for each reaction — by use of the stoichiometric coefficients.
The differential equations are solved numerically for the catalyst effectiveness factor by means of the orthogonal collocation method.
