一种适用于生物柴油-石化柴油掺混油的降凝剂组合物、制备方法及其应用
摘要：
本发明公开了一种适用于生物柴油?石化柴油掺混油的降凝剂组合物、制备方法及其应用。本发明的降凝剂组合物由邻苯二甲酸酯类、乙酸酯类有机溶剂及柴油降凝剂混合而成。具体的，本发明的降凝剂组合物由0?15wt％邻苯二甲酸二甲酯、10?30wt％邻苯二甲酸二乙酯、0?10wt％邻苯二甲酸二丁酯、0?25wt％乙酸丁酯，以及20?60wt％降凝剂组成。其通过将各组分在常温常压下混合搅拌均匀后超声分散25?30min制备得到。本发明的降凝剂组合物尤其适用于由大豆油生物柴油和0#石化柴油在常温常压下混合而成的生物柴油掺混油低温流动性的改进，其降凝效果显著，冷滤点可降低7?11℃，倾点可降低6?10℃。
摘要（英）：

The invention discloses a pour point depressant composition suitable for biodiesel and petroleum diesel blend oil, a preparation method and application of the pour point depressant composition. The pour point depressant composition is formed by mixing phthalic acid ester type organic solvent, acetate type organic solvent and diesel oil pour point depressant. Specifically, the pour point depressant composition is prepared from 0-15 wt% of dimethyl phthalate, 10-30 wt% of diethyl phthalate, 0-10 wt% of dibutyl phthalate, 0-25 wt% of butyl acetate and 20-60 wt% of pour point depressant. By evenly mixing and stirring all the components at normal temperature and normal pressure and conducting ultrasonic dispersion for 25-30 minutes, the pour point depressant composition is prepared. The pour point depressant composition is particularly suitable for improving low-temperature mobility of biodiesel and petroleum diesel blend oil formed by mixing soybean oil biodiesel and 0# biodiesel at normal temperature and normal pressure, the pour point effect is remarkable, the cold filter plugging point can be reduced by 7-11 DEG C, and the pour point can be reduced by 6-10 DEG C.
