چکیده

The elimination of dibenzothiophenes (DBT) from kerosene via the catalytic oxidation desulfurization (ODS) process was studied using hydrogen peroxide as an oxidant and MnO۲/SnO۲ as a catalyst. The oxidation reaction was examined under various operating conditions, including reaction temperatures (۳۰−۷۵oC), batch time (۲۵-۱۰۰ min), and loading amounts of MnO۲ (۰, ۱, and ۵%). The catalysts were conducted in this work using the impregnation method to support MnO۲ nanoparticles on the surface of SnO۲. Mathematical modeling was established by gPROMS software to predict DBT concentration, and kinetic parameters and compare them with observed results. According to the results of this study, it was observed that the maximum DBT removal obtained was ۹۴% under the best operating conditions. The findings showed that the behavior of DBT removal was enhanced with rising temperature, batch time, and MnO۲ loading. The optimal process variables of ODS of DBT based on the maximum conversion of DBT were estimated by an optimization technique. Finally, it can be concluded that the synthesis of nano-catalysts improved the DBT removal and led to the production of ultra-deep desulfurization for eco-friendly kerosene fuel.

اطلاعات بیشتر در مورد COI

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.
