摘　　要：生物柴油是一种可再生能源。以荔枝籽油为原料,以马铃薯废渣中提取的KOH为酯交换催化剂,在微波反应器内合成了生物柴油,研究了KOH含量、甲醇浓度、反应时间和搅拌速率对生物柴油收率的影响。结果表明,提取的KOH可以有效催化荔枝籽油的酯交换反应,当KOH含量为8.75%,甲醇浓度为70%,反应时间为6 min,搅拌速率为600 r/min,荔枝籽油酯交换反应平均收率在89.8%~90.3%,该研究为降低生物柴油制造成本进行了初步探索。Biodiesel is a renewable energy source.Using litchi seed oil as raw material and KOH extracted from potato waste as ester exchange catalyst,biodiesel is synthesized in a microwave reactor.The effects of KOH content,methanol concentration,reaction time,and stirring speed on biodiesel yield are studied.The results show that extracted KOH could effectively catalyze the ester exchange reaction of litchi seed oil.When the KOH content is 8.75%,the methanol concentration is 70%,the reaction time is 6 minutes,and the stirring speed is 600 r/min,the yields of litchi seed oil ester exchange reaction are 89.8%-90.3%.This study can provide a preliminary exploration for reducing the production cost of biodiesel.
