摘要

乙酰丙酸烷基酯可以由可再生的乙酰丙酸合成，具有用作燃料混合物成分的潜力。多种化合物可以与生物柴油混合，以改善或获得所需的燃料特性。本研究评价了乙酰丙酸正丁酯（BL）与棕榈甲酯（PME）共混对燃料性能的影响。用5%、10%和15%的BL制备了BL和PME的共混物（BL-PME）。BL的加入使15BL-PME的浊点和倾点提高了7°C。与生物柴油的ASTM D6751和EN14214规范相比，BL PME在酸值、闪点、运动粘度（40°C）和氧化稳定性方面均符合规范要求。BL的添加量高达15%可提高酸值，降低闪点和运动粘度。添加BL后，氧化稳定性略有提高。BL PMEs的热值随着BL体积的增加而降低。高达10%BL时，热值>35 MJ kg–1。此外，BL与PME高度混溶，未观察到相分离。目前的工作表明BL作为生物柴油的生物基混合燃料化合物具有潜力。

STUDY ON THE EFFECTS OF BLENDING N-BUTYL LEVULINATE WITH PALM METHYL ESTER ON THE FUEL PROPERTIES

Alkyl levulinate can be synthesized from renewable levulinic acid and has the potential to be used as a fuel blend component. A variety of compounds can be blended with biodiesel to improve or attain the desired fuel properties. In this study, the effects of blending n -butyl levulinate (BL) with palm methyl ester (PME) on fuel properties were evaluated. Blends of BL and PME (BL-PMEs) were prepared with 5%, 10% and 15% of BL. The addition of BL has improved the cloud and pour points by 7°C for 15BL-PME. As compared to ASTM D6751 and EN14214 specifications for biodiesel, BL-PMEs revealed properties within the specifications in terms of acid value, flash point, kinematic viscosity (40°C), and oxidative stability. The addition of BL up to 15% increased the acid value and decreased the flash point and kinematic viscosity. The oxidative stability increased slightly upon the addition of BL. The calorific value of BL-PMEs decreased with an increase in BL volume. Up to 10% BL, the calorific value is >35 MJ kg –1 . Besides, BL is highly miscible with PME and no phase separation was observed. The present work suggested that BL has potential as a bio-based fuel blend compound for biodiesel.
