In this study, Euonymus maackii Seed oil (EMSO) was exploited and evaluated for the first time as a new non-edible oil feedstock for preparation of biodiesel. The EMSO yield was 41.06 ± 2.68 wt%. The fatty acid compositions of EMSO involved palmitoleic acid (2.01%), palmitic acid (14.5%), stearic acid (3.1%), oleic acid (49.8%), linoleic acid (29.3%), 11-Eicosenoic acid (0.1%) and arachidic acid (0.07%). Microwave-assisted transesterification with methanol provided a high conversion yield in short duration under low temperature. The 2.0 wt% of catalyst amount, 10:1 of methanol/oil molar ratio, 40 min of reaction time and 60 °C of temperature were found to be the optimum process conditions for the maximum biodiesel yield of 94.74 ± 2.09%. Using pseudo first-order kinetic model, the reaction rate constants were 2.145 × 102, 3.550 × 102 and 6.447 × 102 min−1 for 40, 50 and 60 °C, respectively. The thermodynamic property for biodiesel preparation was determined as activation energy = 47.67 kJ/mol. The fuel properties of the biodiesel product were evaluated and comparable to ASTM D-6751 and EN 14214 standards. Overall, this study revealed and confirmed the potential of Euonymus maackii seed oil as the appropriate alternative feedstock for biodiesel production.

Euonymus maackii Rupr。种子油作为一种新的潜在非食用生物柴油原料

在这项研究中，大叶卫矛籽油 (EMSO) 作为一种新的非食用油原料被首次开发和评估，用于制备生物柴油。EMSO 产率为 41.06 ± 2.68 wt%。EMSO的脂肪酸组成包括棕榈油酸（2.01%）、棕榈酸（14.5%）、硬脂酸（3.1%）、油酸（49.8%）、亚油酸（29.3%）、11-二十碳烯酸（0.1%）和花生酸 (0.07%)。与甲醇的微波辅助酯交换在低温下在短时间内提供了高转化率。发现催化剂用量为 2.0 wt%、甲醇/油摩尔比为 10:1、反应时间为 40 min 和温度为 60 °C 是生物柴油最大产率 94.74 ± 2.09% 的最佳工艺条件。使用拟一级动力学模型，反应速率常数分别为 2.145 × 102、3.550 × 102 和 6。40、50 和 60 °C 分别为 447 × 102 min-1。生物柴油制备的热力学性质确定为活化能 = 47.67 kJ/mol。生物柴油产品的燃料特性经过评估，可与 ASTM D-6751 和 EN 14214 标准相媲美。总体而言，这项研究揭示并证实了卫矛籽油作为生物柴油生产的合适替代原料的潜力。
