Abstract

Currently, biotransformer oil (BTO) is in high demand due to the increasing level of electrical power consumption and environmental policy. Hence, this research aimed to prepare a highly stable BTO via basic transesterification of palm oil methyl ester (POME) and ditrimethylolpropane (Di-TMP) catalyzed by sodium methoxide (NaOCH₃). Under the optimal conditions (POME/Di-TMP molar ratio = 5.0/1.0, NaOCH₃ loading = 8 mol % based on the Di-TMP content under 3.5 mbar, and 300 rpm at 160 °C for 2 h), the POME conversion level and POME-Di-TMPTTE selectivity reached 90.3% and 96.6%, respectively. The obtained BTO with a high POME-Di-TMPTTE portion exhibited greater oxidation stability with a higher flash point and breakdown voltage in accordance with the IEC 62770 specification. A techno-economic analysis revealed the possibility of POME-Di-TMPTTE as a commercial BTO for its competitive cost and profit based on the current commercial price of BTO.

棕榈油甲酯和二三羟甲基丙烷酯交换反应生成的高稳定性生物转化油的合成、特性和技术经济分析

目前，由于电力消费水平和环保政策的不断提高，生物变压器油（BTO）的需求量很大。因此，本研究旨在通过甲醇钠（NaOCH3）催化棕榈油甲酯（POME）和二三羟甲基丙烷（Di-TMP）的基础酯交换反应制备一种高度稳定的 BTO。在最佳条件下（POME/Di-TMP 摩尔比 = 5.0/1.0，NaOCH3 负载 = 8 mol %（基于 3.5 毫巴下的 Di-TMP 含量），300 转/分钟，160 °C，2 小时），POME 转化率和 POME-Di-TMPTTE 选择性分别达到 90.3% 和 96.6%。获得的具有较高 POME-Di-TMPTTE 部分的 BTO 具有更高的氧化稳定性，闪点和击穿电压也更高，符合 IEC 62770 规范。技术经济分析表明，根据目前 BTO 的商业价格，POME-Di-TMPTTE 的成本和利润具有竞争力，因此有可能成为一种商业 BTO。
