Abstract

The aim of this study was to develop an appropriate kinetic model for propane dehydrogenation (PDH) over an industrial Pt–Sn/γ-Al2O3 catalyst in the presence of small amounts of oxygenated compounds. Experimental data were obtained from a previous study where catalytic PDH was carried out in a laboratory scale reactor at atmospheric pressure in the temperature range of 575–620 °C in the presence of small amounts of water or methanol. The kinetics of the main dehydrogenation reaction was described and the effects of water and methanol on coke deposition and catalyst sintering were considered in a catalyst deactivation model to explain the observed optimum level in the amount of added oxygenated compounds. The model predictions were in good agreement with experimental data.
