甲醇汽油的馏程特性研究

Research of Distillation Range Characteristics on Methanol-Gasoline

低比例甲醇汽油的馏程特性试验研究结果表明:当甲醇含量不大于30%时,甲醇汽油的10%馏出温度普遍低于汽油;M5、M10甲醇汽油的50%馏出温度与汽油变化不大,M15、M20、M30甲醇汽油的50%馏出温度比90#汽油明显降低;甲醇汽油的90%馏出温度与90#汽油变化不大。甲醇含量不大于10%的甲醇汽油具有满意驾驶特性的馏程特性,含量不大于30%的甲醇汽油有较好的适用性。

The experimental research results of distillation range characteristics on low proportional showed ： as the proportional of methanol is lower than or equal to 30%, the temperature of 10% distillation range is lower than gasoline＇s; the temperature of 50% distillation range of M5 and M10 methanol-gasoline are about the same as gasoline＇s and those of M15, M20 and M30 methanol-gasoline decrease obviously than gasoline＇s; the temperature of 90% distillation range is similar with gasoline＇s. Methanol-gasoline has satisfied driving property of distillation range characteristics as the proportion of methanol is low or equal to 10%, and methanol-gasoline has better suitable property as the proportion of methanol is lower than or equal to 30%.
