چکیده

 با افزودن انواع نانومواد به سوخت‌ پایه دیزل، سوخت‌های غنی شده با نانومواد یا به‌طور خلاصه نانوسوخت حاصل می‌‌شود. این افزودنی‌ها به دلیل خصوصیات منحصربه‌فرد نانومواد، می‌‌توانند به طور قابل‌توجهی بر خصوصیات و رفتار سوخت تأثیر بگذارند. چگالی سوخت، گرانروی سینماتیکی، نقطه اشتعال و ارزش حرارتی برای سوخت‌‌های پایه و نیز برای نانوسوخت‌ها، از ویژگی‌های احتراق سوخت دارای اهمیت است. افزودن نانوذراتی مانند اکسیدگرافن و اکسید منگنز باعث بهبود خواص می‌شوند، این اثرات ممکن است متفاوت باشند اما علاوه بر این، نانومواد افزودنی می‌توانند رسانایی حرارتی و سرعت تبخیر سوخت پایه را بهبود ببخشند. هدف از انجام این تحقیق، مطالعه خواص فیزیکی-شیمیایی سوخت دیزل حاوی نانوذرات منگنزاکساید (MnOX) سنتز شده با غلظت ppm100 و گرافن‌اکساید (GO) با غلظت‌‌های ppm20 و 10 و هیبرید آنها است. تغییرات جزئی خواص فیزیکی شامل چگالی و گرانروی به ترتیب به میزان 2/0% و 6/0% برای نانودیزل‌های تهیه شده و نیز افزایش 7/7% ارزش حرارتی سوخت توسط بمب کالری‌متری برای نانودیزل حاوی نانوذرات هیبریدی منگنز اکساید وگرافن اکساید به صورت کاملاً معلق و پایدار، گزارش شده‌ است. از طرف دیگر آنالیزهای FESEM، BET و EDS برای مشخصه‌یابی سایز، مورفولوژی، مساحت سطح و درصد عناصر تشکیل دهنده نانوذرات، به‌کار گرفته شده است.

چکیده [English]

By adding nanomaterials to various diesel engine base fuels, one gets nanomaterials enriched fuels, or nanofuels in short. This addition may influence significantly the properties and behavior of the fuel due to unique properties of nanomaterials. The main purpose of this research is to study the physico-chemical properties of diesel fuel containing NPs of Manganese Oxide (MnOx) synthesized with a concentration of 100 ppm and Graphene Oxide (GO) with concentrations of 10 and 20 ppm and also by their hybrids. In this regard, the partial changes in the physical properties of density and viscosity in nanofuels by the concentrations of 0.2% and 0.6%, respectively have been observed.  The study also is based on the effect of nanometal oxide additives like Manganese Oxide and Graphene Oxide to diesel fuel. Metal oxide additive are doped with diesel fuel. The changes in diesel fuel properties (viscosity, flash point and fire point) due to introduction of nanometal oxide additive were observed. The diesel fuel with nanometal oxide additive presented a marginal increase in performance. Exhaust emissions for the diesel fuel with nanometal oxide additive showed significant decrease in levels of pollutants emission.
