Description
技术领域
本发明属于燃料技术领域,特别涉及一种车用生物燃料。
背景技术
生物柴油(Biodiesel)是一种较为洁净的合成油,普遍用于拖拉机、卡车、船舶等。它是指以油料作物如大豆、油菜、棉、棕榈等,野生油料植物和工程微藻等水生植物油脂以及动物油脂、餐饮垃圾油等为原料油通过酯交换或热化学工艺制成的可代替石化柴油的再生性柴油燃料。
生物柴油是生物质能的一种,其在物理性质上与石化柴油接近,但化学组成不同。生物柴油是含氧量极高的复杂有机成分的混合物,这些混合物主要是一些分子量大的有机物,几乎包括所有种类的含氧有机物,如:酯、醚、醛、酮、酚、有机酸、醇等。
但是生物柴油燃使用时会产生易结胶、积碳等问题,多年以来始终困扰着业界技术人员。在发动机燃烧室内,生物柴油又比石油柴油更容易产生积碳,导致汽缸压缩比升高、燃烧环境持续恶化,造成燃烧不充分,造成发动机磨损严重、温度升高,车辆油耗快速增加,积碳造成进气阀燃油吸附和喷油嘴雾化不完全,从而造成发动机的动力损失。此外,生物柴油存放时间短易变质,变质后的生物柴油其酸度会增加,对发动机腐蚀性大。
发明内容
本发明所要解决的技术问题是提供车用生物燃料,该车用生物燃料不容易积碳,且保质期较长。
为实现上述目的,本发明采用如下技术方案:
本发明提供车用生物燃料,由以下重量份的原料制成:生物柴油60-80份,2,2-二异戊醚-1,3-丙二醇8-15份,丙二醇丁醚8-12份,三烯丙基胺3-8份,单硬脂酸甘油酯1-5份,二甲基乙酰胺1-5份。
优选地,本发明所述的车用生物燃料,由以下重量份的原料制成:生物柴油65-75份,2,2-二异戊醚-1,3-丙二醇10-13份,丙二醇丁醚9-11份,三烯丙基胺4-6份,单硬脂酸甘油酯2-4份,二甲基乙酰胺2-4份。
更优选地,本发明所述的车用生物燃料,由以下重量份的原料制成:生物柴油70份,2,2-二异戊醚-1,3-丙二醇12份,丙二醇丁醚10份,三烯丙基胺5份,单硬脂酸甘油酯3份,二甲基乙酰胺3份。
优选地,本发明所述的生物柴油的制备方法为:取植物油,加入甲醇和氢氧化钾,混合均匀,在55-70℃下反应1.5-2.5h,将反应混合物倒入分液漏斗进行分离,分出下层甘油,将上层产物蒸馏脱除甲醇,温水洗涤至中性,再经蒸馏,即可得到生物柴油。
优选地,本发明所述的植物油为棕榈油、菜籽油、棉籽油、大豆油、蓖麻油中的一种。
优选地,本发明所述植物油与甲醇的体积比为5:2-3。
优选地,本发明所述氢氧化钾的加入量为植物油质量的0.8-1.2%。
