当前的能源危机极大地影响了世界经济发展。因此，确定新能源资源至关重要。在这项研究中，我们介绍了一种潜在的生物柴油来源：大头金蝇幼虫(CML)，它们具有增殖性，可以用各种低成本材料喂养，如粪便、麦皮、腐肉和腐烂的植被。探讨了巨头涡虫幼虫油(CMLO)在生物柴油中的应用潜力。从以餐馆垃圾为食的CML中提取了5天的油。由于餐饮垃圾的成分每天都不同，从脱水CML中获得的含油量在24.40%到26.29%之间。测得CMLO的酸值为1.10 mg KOH/g。随后考虑了四个因素对CMLO的酯交换反应进行了优化。最佳反应条件为醇油摩尔比为6：1，催化剂用量为1.6%，反应温度为55℃，反应时间为30min。在此条件下，CMLO合成脂肪酸甲酯(FAME)的最高产率为87.71%。最后，FAME的性能符合ASTMD6751和EN 14214生物柴油标准。因此，我们认为大头节幼虫是生产生物柴油的一种潜在的替代原料。(C)2012爱思唯尔有限公司。保留所有权利。
The current energy crisis greatly affects worldwide economic development. Therefore, identifying for new energy resources is critically important. In this study, we introduce a potential biodiesel source: Chrysomya megacephala (Fabricius) larvae (CML), which are proliferative and can be fed with a variety of low cost materials, such as manure, wheat bran, rotted meat and decayed vegetation. The potential of C. megacephala (Fabricius) larvae oil (CMLO) for biodiesel applications was explored. Oil was extracted from the CML raised by feeding on restaurant garbage for five days. The oil content obtained from the dehydrated CML ranged from 24.40% to 26.29% since restaurant garbage varies in composition day to day. The acid value of the CMLO was tested to be 1.10 mg KOH/g. Four factors were subsequently considered to optimize the transesterification of CMLO to biodiesel. The optimized conditions included a 6:1 methanol to oil molar ratio, 1.6% KOH catalyst, a reaction temperature of 55 degrees C and a reaction time of 30 min. Under these conditions, the maximum yield of fatty acid methyl esters (FAME) from CMLO was 87.71%. Finally, properties of the FAME were within the specifications of ASTM D6751 and EN 14214 biodiesel standards. Therefore, we concluded that C megacephala (Fabricius) larvae represent a potential alternative feedstock for biodiesel production. (C) 2012 Elsevier Ltd. All rights reserved.
