چکیده

در طول سال­ های اخیر، با توجه به شرایط آب وهوایی مطلوب ایران، کشت کلزا به میزان قابل توجهی افزایش یافت، به­ طوری که در سال 2010 تولید کلزا در ایران به 145900 تن در سال بود که در سال 2013 به 174999 تن در سال رسید. هدف از این تحقیق بررسی امکان تولید بیودیزل از روغن کلزای غیرخوراکی با استفاده از سامانه فراصوت است. در این تحقیق، چهار فاکتور مختلف، ازجمله نسبت مولی، زمان واکنش، پالس و دامنه، در سه سطح درنظر گرفته شد. برای تجزیه و تحلیل آماری از نرم ­افزار Designe Exeprt، روش سطح پاسخ (RSM) و طرح  Box Behnken  برای شناسایی شرایط مطلوب روند استفاده شد. پس از تجزیه و تحلیل داده­ ها و بهینه­ سازی واکنش تولید بیودیزل نتیجه تحقیق نشان داد که در شرایط بهینه تولید بیودیزل در نسبت مولی 87/1:4، زمان واکنش77/3 دقیقه، پالس 58/99 درصد و دامنه 5/73 درصد، بازده واکنش 26/89 درصد به دست آمد. خواص فیزیکی و شیمیایی بیودیزل تولیدشده با استاندارد EN 14112 مطابقت دارد و نشان­دهنده این است که بیودیزل تولیدشده دارای عملکرد قابل قبولی است و می­ توان به­ عنوان سوخت جایگزین در موتور دیزل استفاده کرد.
