【摘要】 本文研究了超临界CO2、微波和超声波萃取光皮树果实油技术及以所获得的光皮树果实油通过酯交换法制取生物柴油的工艺。通过L₉（3⁴）正交试验来确定光皮树果实油酯交换反应的最优条件。结果表明:三种提取方法都能得到光皮树果实油,并且都可用作生物柴油制取的原料油。超临界CO₂萃取得率34.79%;微波萃取得率28.12%;超声波萃取得率27.75%;酯交换反应的最佳工艺条件是A1B3C2D3,即甲醇:油=5∶1（物质的量之比）、催化剂的用量是1.1%、反应温度为60℃、反应时间100min,且三种提取方法获得的光皮树果实油的酯交换转化率分别为:超临界CO₂萃取95.6%;微波萃取92.69%;超声波萃取91.79%。更多还原

【Abstract】 Feedstocks for biodiesel production have been focused on all through out of the world..The technical conditions for extracting oil from Swida wilsoniana’ fruits separately by supercritical CO₂,microwave and supersonic wave were optimized and compared. An orthogonal design experiment L9（3⁴） was used to optimize the transesterification conditions.The results show that: the three methods can all process oil from Swida wilsoniana’ fruits into biodiesel. And the optimal extracting rates from Swida wilsoniana’seeds are as follows: 34.79%, 28312% and 27.75%.The optimal conditions for the transesterification are A1B3C2D3,ether as solvent,ratio of solvent to material 5:1, The consumption of the catalyst is 1.1% the,temperature 60℃,and the time 120min.And the converting rate of three methods attaining oil from Swida wilsoniana fruits, supercritical CO₂,microwave and supersonic wave, is in turn 95.6%,92.69% and 91.79%.更多还原
