摘　　要：针对生物柴油调合生产过程中由于酸含量测试方法差异而引起质量波动的问题,分析了GB/T 264-1983、GB/T 4945-2002、GB/T 7304-2000、GB/T 258-1988、GB/T 5530-2005、GB/T 9104-2008等涉及矿物柴油、生物柴油、抗磨剂等调合组分的质量标准中酸含量测试方法中的溶剂、滴定剂、终点判定等因素,指出了不同方法的优势和使用体系。生物柴油调合燃料(B5)生产中原料酸含量表征方式的不统一,密度的差异影响产品酸值合格率的控制。统一酸含量表征方式,选用适宜的试验方法,调整酸含量内控指标,根据矿物油密度优化调合比对控制生物柴油调和燃料(B5)酸值指标、稳定产品质量具有积极作用。Regarding to the problem that different acid content determining methods lead to the quality fluctuation of blended biodiesel fuels during the blending process, the acid content determining methods in GB/T 264-1983,GB/T 4945-2002,GB/T 7304- 2000,GB/T 258-1988,GB/T 5530-2005,GB/T 9104-2008 which involve the quality standards of the mineral diesel, biodiesel, anti- wear agents of the blended biodiesel fuel components are analyzed, and it is pointed that different acid content determining methods have their own advantages and use system. In the production of blended biodiesel fuel （B5）, no unified expression of acid content in the materials and the difference in the density of the materials will influence the acid value pass-rate. The unified expression of acid content, the suitable determining method of acid value, the adjustment of acid content, the optimization of blending ratio all have pos- itive effects on the acid content indicator control and the quality stability of biodiesel fuel products （BS）.
