| چکیده | ||
| در این پژوهش، کانمیت از خاکستر پوسته برنج تهیه شده، و به عنوان یک کاتالیزور ناهمگن بازی برای تولید بیودیزل از روغن آفتابگردان استفاده شد. خصوصیات کاتالیزور با استفاده از تکنیکهای PXRD، FESEM و FT-IR شناسایی گردید. پارامترهای موثر در واکنش ترانس استریفیکاسیون برای تولید بیودیزل از قبیل مقدار کاتالیزور، نسبت مولی متانول به روغن، زمان واکنش و دمای واکنش بهینه شد. تحت شرایط بهینه (% 5 وزنی کاتالیزور، نسبت مولی متانول: روغن 1:24، زمان واکنش 4 ساعت و دمای C° 65 ) درصد تبدیل به 2/97 رسید. همچنین کاتالیزور 5 بار بدون کاهش قابل توجه در درصد تبدیل، قابلیت بازیابی و استفاده مجدد را دارد. | ||

| چکیده [English] | ||
| In this work, Kanemite was prepared from rice husk ash and used as a heterogeneous base catalyst for production of biodiesel from sunflower oil. The catalyst was characterized by PXRD, FESEM and FT-IR. The transesterification conditions, such as the catalyst dosage, molar ratio of methanol to oil, reaction temperature and reaction time were investigated and optimized. The results revealed that by a catalyst loading of 5 wt. %, methanol to oil ratio of 24:1, reaction temperature of 65 °C and reaction time of 4h, conversion of biodiesel reached 97.2%. Moreover, the catalyst could be reused up to five cycles under the optimum reaction conditions without significant loss of product yield. | ||
