Abstract

In this study, "WATER-GAS SHIFT REACTION" which is, an exothermic reaction aimed at production of hydrogen and reduction of CO level in gas reaction, as well as mechanism and KINETIC MODELS of this reaction on platinum catalyst have been calculated. Two types of redox and associative mechanisms based on Langmuire-Hinshelwood and Eley-Rideal models have been considered in the range of 573-723K. Fifteen kinetic model based on the rate-limiting step were derived and they were compared with each other by using suitable objective function and GENETIC ALGORITHM. In view of very minor calculation’s error, variation in rate constants based on Arrhenius and Vant-Hoff equation were achieved. Finally amongst submitted models, kinetic model based on redox mechanism and Langmuire-Hinshelwood model which had the least error were recommended as the best model.
