✦ Synopsis

The regeneration of fixed bed catalytic reactors has been simulated using a pseudo-homogenous model. The influence of a number of variables on the temperature rise has been studied. In particular the effect of coke content and composition have been determined. It was found that fixed beds with series and parallel types of coke distribution behave differently when these variables are changed. Regeneration policies in which a stepped oxygen feed is employed, are discussed.

This report gives results of studies to find the numerical solution of a model representing fixed bed burning. Two well known approximating methods were used. They were (1) a first-order method and (2) the use of a second-order polynomial approximation. Truncation error studies were made to compare
