Abstract:

The biodiesel has been successfully produced in a self-designed microwave reactor in laboratory by employing a novel carbon?鄄based acid catalyst prepared via the combination of carbonization and sulfonation process. This work exhibit a potential application of microwave-assisted acid catalyst in biodiesel preparation. The catalyst presented a high efficiency and good stability under microwave treatment with which the reaction was significantly accelerated. The optimization of reaction condition was first studied by a single factor method. The factors which affected the conversion efficiency of biodiesel，such as microwave power density，microwave reaction time，and catalyst amount，were determined accordingly using the response surface analysis. The optimized condition was processed as microwave power density of 1.15 W/mL for 33.33 min with 4.83% catalyst which gave a 90.38% ester yield. This optimized result was consistent with the previous results from the single factor experiments and this model was confirmed with higher reliability and better fitting.
