Abstract    This study explores the potential of titanium oxide impregnated on calcium oxide (CaO-TiO2) as catalyst in transesterification of vegetable palm oil (VPO) to produce biodiesel. The biodiesel yield increased with catalyst calcination temperature and reaction time, and the usage of CaO-TiO2 led to higher biodiesel production when compared to reaction catalyzed by CaO. Biodiesel yield of 93.33% was recorded when CaO-TiO2 was used at optimized reaction conditions. Catalyst characterizations showed that addition of TiO2 to CaO improved the catalytic property by increasing the surface area and strength of basic sites, hence increased the catalytic performance of TiO2-CaO. This study demonstrates the potential of CaO-TiO2 to convert VPO into biodiesel, and the potential of the catalyst in conversion of waste cooking oil into renewable fuel will be studied.

چکیده    این تحقیق، پتانسیل اکسید تیتانیوم آغشته به اکسید کلسیم (CaO-TiO2 كه به عنوان کاتالیزور در انتقال الیاف روغن هاي نباتي روغن نخل سبزیجات(VPO) برای تولید بایودیزل استفاده مي شود را مورد بررسی قرار می دهد. عملکرد بایودیزل با دمای کالیبراسیون کاتالیزور و زمان واکنش افزایش یافته و استفاده از CaO-TiO2 باعث افزایش تولید بایودیزل در مقایسه با واکنش کاتالیز شده توسط CaO مي شود. هنگامی که CaO-TiO2در شرایط واکنش بهینه سازی شده استفاده شد, بايوديزل بازدهي به مقدار 93.33% را به دست آورد. تعاریف کاتالیستی نشان داد که افزودن TiO2 به CaO, به دلايلي مثل افزایش سطح كاتاليزور و همچنين افزايش قدرت سایت های فعال كاتاليزور, خواص کاتالیزوری را افزايش داده كه باعث افزايش عملكرد كاتاليزوري CaO-TiO2 مي شود. این مطالعه پتانسیل CaO-TiO2 به منظور تبديل VPO به بايوديزل و همچنين توانايي كاتاليزور را به منظور تبديل پسماند روغن مصرفي (نباتي) به سوخت تجدید پذیررا نشان مي دهد.
