Abstract

On the basis of the identification of the elementary step sequence on the active surface of the catalyst

a series of transient response experiments with step changes in feed composition were carried out

by measuring the variation of the tail - gas composition of the micro - reactor with an on - line FTIR detector. A transient model of the reactor was developed. The values of the kinetic parameters for all elementary steps were estimated by fitting the solution of the model with experimental response data. The results showed that the prediction of the model is qualitatively consistent with experimental observation.
