| description | AbstractCatalysts are involved in many industries and due to their high cost, therefore, the research was directed to the exploitation of environmentally friendly materials, which are the natural raw materials that are available in large quantities in the Western Desert region of Anbar, in the preparation of the catalyst support material under study (alumina). Where the ore was exploited after conducting a series of treatments to prepare alumina as a dominant material for the catalyst prepared from platinum and palladium. The catalyst was used in the gaseous treatment of naphtha (58 - 160 °C) at different conditions of temperature, reaction time and the percentage of catalyst added, and after determining the optimal conditions for the catalytic treatment by analyzing the results of infrared (IR) measurement according to the initial conditions, it was found that the best treatment conditions were at a temperature of (250 °C), a reaction time of (2 hours), and a catalyst ratio of (2%), where the catalyst showed high effectiveness towards the reactions of structural reformation and hydrogen removal, in addition to that, a nuclear magnetic resonance spectroscopy (NMR) was measured ( 1HNMR) and gas chromatography (GC) for both untreated and treated naphtha under optimal conditions for the purpose of identifying the nature of structural changes of different hydrocarbon compounds (PONA) and estimating the ratio of methylene, methylene and aromatic protons, respectively. The results showed the effectiveness of the catalyst towards the reactions of structural reforming and dehydrogenation through the formation of aromatic and olefinic compounds. |
