چکیده
این مطالعه به بررسی کاربرد کاتالیست LECA@OH-W3O10 (لیکای عاملدار- اکسید تنگستن) به عنوان کاتالیزور برای تولید بیودیزل می‌پردازد. کاتالیزور با استفاده از تکنیک­های مختلف از جمله XRD، FESEM، FTIR، TEM و BET-BJH مشخصه‌یابی شد. نتایج مشخصه‌یابی نشان داد عاملدار کردن LECA با گروه­های OH موجب افزایش سطح فعال و در دسترس برای بارگذاری W3O10 ایجاد کرده است. کاتالیزور LECA@OH-W3O10(0.3) دارای حجم منافذ cm3/g 0/0256، متوسط قطر حفرات nm 9/6 بوده و طبق آنالیز FESEM و TEM از پراکندگی خوب فاز فعال W3O10 روی سطح LECA@OH برخوردار است. در شرایط فرایندی %­3 وزنی کاتالیست، دمای °C 95، زمان 2 ساعت و نسبت مولی متانول به روغن 20، این کاتالیست 91/28 درصد تبدیل داشت.

چکیده English

This study investigates the application of W3O10-LECA@OH (functionalized LECA-tungsten oxide) as a catalyst for biodiesel production. The catalyst was characterized using various techniques including XRD, FESEM, FTIR, TEM, and BET-BJ. The characterization results showed that functionalizing LECA with OH groups increased the active surface area and achieved W3O10 loading. The W3O10(0.3)-LECA@OH catalyst had a pore volume of 0.0256 cm3/g, an average pore diameter of 9.6 nm, and FESEM and TEM analysis showed good dispersion of the W3O10 active phase on the LECA@OH surface. Under the catalyst conditions of 3 wt% catalyst loading, 95 °C temperature, 2 h time, and 20 mol ratio of methanol to oil, this catalyst achieved 91.28% conversion.
