| Summary, etc. |
Propylene is widely used in industry as a starting material for many downstream petrochemical productions in particular polypropylene. It is produced by catalytic dehydrogenation process near atmospheric pressure and 580-650 °C over Pt-Sn/Al2O3 catalyst. However, there are also many undesired reactions occur notably formation of carbon due to high temperature hydrocarbon decomposition. Physicochemical characters including element quantity and quality, nature, morphology, structure and location of coke deposited on used Pt-Sn/Al2O3 catalyst were studied by several characterization techniques i.e. Liquid Nitrogen Physisorption, X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS), Field Emission Scanning Electron Microscope (FESEM) and Thermogravimetric Analysis (TGA). XPS analysis detected the constituents of the catalyst and also other elements i.e. K, S, Cl and Fe. FTIR identified the presents of various hydrocarbon species particularly dehydrogenated species; olefins and aromatics while crystallite pre-graphite which indicates the coke was detected by XRD. FESEM images also proved the presents of coke in amorphous, whiskers-like form. BET surface for coked catalyst was only 78.943 m2 g-1. The coke formed was altered by Sn promoter towards the bulk alumina support as discovered by TGA. Subsequently, for carbon removal analysis, the highest gasification obtained as oxygen and followed by air. Nitrogen gasified coke with the lowest rate and the activation energy for nitrogen is higher than oxygen and air. Air is suitable gasifying agent as it can removed carbon content like oxygen but in a mild condition with lower heat released. Different heating ramps did not affect the gasification mechanism. |
