Research of Synthesizing Biodiesel from Suaeda Salsa by Ultrasonic-Assisted Transesterification
Suaeda salsa oil was taken as raw materials to produce biodiesel by ultrasonic-Assisted transesterification. Single factor experiment and the orthogonal experiment combination design were adopted to study the effects of ultrasonic frequency, ultrasonic power，reaction temperature ，reaction time，catalyst dosage and mole ratio of methanol to oil on biodiesel production rate. The order of factors that influence the biodiesel production rate within the experimental range was as follows: catalyst dosage＞reaction time＞reaction temperature＞mole ratio of methanol to oil. The optimal technological parameters should be as follows: ultrasonic frequency 28kHz, ultrasonic power 210W, reaction temperature 65 , reaction time 10min,catalyst dosage 0.3%and mole ratio of methanol to oil 6, and biodiesel production rate is 97.93% under such conditions.
