چکیده

در این تحقیق یک مخلوط نانوساختار فلزی CaO/talc با روش ساده تلقیح مرطوب سنتز شد. نانوکاتالیست تهیه‌شده در واکنش تبادل استری شدن روغن کانولا و متانول برای تولید زیست‌گازوییل استفاده شد. تأثیر دمای کلسیناسیون و دمای واکنش روی فعالیت کاتالیست در واکنش بررسی شد. همچنین سرعت واکنش با یک مدل سینتیکی مطالعه گردید و پارامترهای سینتیکی محاسبه شد. مشخصه‌های سطحی و ساختاری کاتالیست با استفاده از طیف‌سنج پراش اشعه ایکس XRD، آنالیز توزین حرارتی/مشتق توزین حرارتی TG/DTG و مطالعات مساحت برونر، امت، تلر BET بررسی گردید. این مطالعات نشان داد که عملکرد بهینه نانوکاتالیست در اثر تولید مراکز فعال در سطح کاتالیست و بهبود ساختار آن می‌باشد.
