Development and verification of a simulation model for a non-isothermal water-gas shift reactor

Abstract

A fixed-bed test reactor suitable for studying non-isothermal reaction kinetics was developed. The reactor allows axial and radial temperature measurem The water-gas shift reaction over a commercial iron-based catalyst was chosen as the subject of a case study. A non-isothermal reactor operating at tem with feed compositions corresponding to industrial conditions was used. A method of sequential regression analysis was applied to determine the kinetic conversion profiles of the bed. The experimental data could be fitted by a power-law type of reaction rate expression. The rate equation combined with successfully used to predict the fixed-bed behaviour within large temperature, concentration and space velocity intervals.
