摘要: 生物柴油调合燃料的氧化安定性是一个非常重要的指标。本文介绍了多种可用于测定生物柴油调合燃料氧化安定性的标准方法,比较了各种方法的差异及各自的优缺点,并且指出馏分燃料加速氧化法即石化行业标准 SH/T 0175(ASTM D 2274)以及油脂稳定指数法即 Rancimat 法(EN 14112)是可能被普遍采用,并作为生物柴油调合燃料产品标准中氧化安定性指标的指定分析方法。其它标准方法如馏分燃料 43℃ 贮存氧化法(SH/T 0690,ASTM D 4625)、高温稳定性评价法(ASTM D 6468)、 JFTOT法(GB/T 9169,ASTM D 3241)以及汽油诱导期法(GB/T 8018,ASTM D 525)可作为研究生物柴油调合燃料氧化安定性的辅助方法。同时对我国正在制定的生物柴油调合燃料B5和即将制定的B10、B20国家标准中氧化安定性指标和方法提出了建议。

Abstract: Oxidation stability is one of the most important properties of biodiesel blend fuels. Various standard test methods to evaluate the oxidation stability of biodiesel blend fuels were presented and compared in this paper. It is indicated that the accele-rated oxidation method of distillate fuel oil (ASTM D 2274 or SH/T 0175) and oil stability index (OSI) method (EN 14112) were two widely accepted standard methods which might be specified in a variety of biodiesel blend fuel specifications. Other standard methods such as distillate fuel storage at 43℃ method (SH/T 0690 or ASTM D 4625), high temperature stability method (ASTM D 6468), JFTOT method(GB/T 9169 or ASTM D 3241)and gasoline induction period method (GB/T 8018 or ASTM D 525)could also be useful methods to study the oxidation stability of biodiesel blend fuels. Suggestions are given to specify the oxidation stability of the coming draft national specifications of B5,B10 and B20 as well.

Key words: biodiesel blend fuels, oxidation stability, test method
