Diesel fuel mixtures with high concentrations of biodiesel have been investigated to analyze the technical feasibility of their use in diesel cycle engines regarding thermal and oxidative properties. The results of combined techniques of oxidative stability, high Pressurized Differential Scanning Calorimetry (P-DSC), Calculated Cetane Index (CCI), and calorific power were used to verify the effect of the thermal-oxidative stability as a function of the percentage of biodiesel in the mixtures. The obtained results evidenced that the thermal and oxidative stability decreased with the addition of biodiesel from 50 to 5% v/v. Low stability fuels require rapid use as the oxidation compounds degrade the product and impair vehicle performance, as well as lead to corrosion and clogging problems in various mechanical systems.

加压差示扫描量热法测定生物柴油/石油柴油混合物的热氧化稳定性及其十六烷值计算值

已经对具有高浓度生物柴油的柴油燃料混合物进行了研究,以分析其在柴油循环发动机中使用的热和氧化性能的技术可行性。结合使用氧化稳定性,高压差示扫描量热法(P-DSC),十六烷值计算值(CCI)和热功率的组合技术来验证热氧化稳定性对生物柴油百分比的影响在混合物中。获得的结果表明,随着生物柴油的添加,热稳定性和氧化稳定性从50%降至5%v / v。低稳定性燃料需要快速使用,因为氧化化合物会降低产品质量并损害车辆性能,并导致各种机械系统出现腐蚀和堵塞问题。
