چکیده

Reformulated gasoline must maintain a high-octane rating with reduced aromatic and olefin content. In the production of gasoline from naphtha, C5 and C6 n-paraffin’s are typically isomerizes to their branched isomers, which have a higher octane rating. ZSM-5 zeolites are the well-known solid acid catalysts and have been widely used in the fuel-upgrading and production of many petrochemicals, due to its unique structures, thermal stability, acidity and shape selectivity.In this work, Na-ZSM-5 zeolite was successfully synthesized via hydrothermal method at relatively low crystallization time. The Pt-promoted ZSM-5 with nominal loading of 1 wt% wereprepared by impregnation method. The obtained catalyst samples were characterized by XRD,SEM, EDAX, UV and FTIR analysis. X-ray diffraction and FTIR results confirmed the formation of ZSM-5 crystal and scanning electron microscopy images revealed the morphology of the prepared zeolite

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
