This research was carried out following the high demand of propylene as a precursor to polypropylene plastic and packaging materials as a trending problem to the packaging industries. Its main focus is on kinetic modeling and Design of an Autoclave reactor for the dehydrogenation of propane to propylene. its aim is to develop an appropriate kinetic model for propane dehydrogenation (PDH) Over an industrial pt - Sn/c - A1203 Catalyst in the presence of small amounts of Oxygenated Compounds Experimental data were obtained from a previous where catalytic PDH was carried out in a laboratory scale reactor at atmosphere 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 deposit ion and catalyst sintering were considered in a catalyst deactivation model to explain the observed optimum level in the amount of added oxygenated compounds. Analysis of the designed autoclave reactor was assessed equivalently to the performance evaluation of the autoclave reactors for dehydrogenation of propane at Variant process temperature using MATLAB algorithm and programming integrations. The volume of the propylene formed from the system increases with increase in the reactors process temperature. Same as the depletion rate those such that there is a Ore accelerative proportional in Crease in the propylene volume from 34.8205 m³ 24.3744m³, 31.3385 m³ 51.4815 m³, 66.1906 m³ within 60% to 90% fractional Conversion of the system, assessed on the basis of Variant temperatures 250°C, 350°C and 450°C respectively.
