Research of Preparation of SO₄^2-/TiO₂-ZrO₂ and its Application on Synthesis of Biodiesel from Waste Cooking Oil

Abstract:

SO42-/TiO2-ZrO2 was prepared by coprecipitation and dipping methods, and characterized by FT-IR, BET surface area measurement and NH3-TPD, and those results demonstrate the SO42- was loaded on the catalyst and the catalyst have enough surface area and pore size. The effect of methanol oil mole ratio, catalyst dosage, reaction temperature, reaction time on the conversion of waste cooking oil to biodiesel was investigated to find optimum reaction conditions. From the orthogonal experiments, the optimum reaction condition was shown as follows: methanol oil mole ratio is 25:1, catalyst dosage is 5% of oil, reaction temperature is 120°C, reaction time is 8h, the yield reached 96.68%.
