Description

一种汽车用低油耗费托合成粗液蜡醇醚燃料
技术领域
本发明涉及节能环保燃料技术，具体是一种汽车用低油耗费托合成粗液蜡醇醚燃料。
背景技术
目前因石油进口额度高达57%,其安全限度大幅超过30%,以及中国“煤多油少”格局,煤制甲醇费托合成石脑油供大于求等大环境因素,甲汽油汽油掺甲醇方式的“甲醇汽油”以其环保,节省石油资源等优势,已成为新能源投资热点,全国各地的甲醇汽油项目已多见报道,但目前成功者寥寥无几,由于甲醇汽油地方标准的缺陷缺少“热值”项目的检测,就导致了甲醇汽油发展路线多支,配方千变万化,专利技术花样繁多,每个都可以使用,而且都可以符合“标准”,能否被市场认可,实际上则必须应具备两大“硬”指标:一是“油耗”问题:能否做到和国标水汽油持平,二是成本问题:即甲醇比例是否足够高,“油耗”必须做到和国标示汽油持平。如果油耗大于汽油,则导致发动机空燃比的降低,空燃比是发动机正常工作的关键指标,改变空燃比,就会导致发动机不能正常工作，在最佳状态,如果甲醇汽油热值低,则油耗大,发动机空燃比降低,动力提速弱,反之,则油耗小,空燃比增加,动力强劲,但会使燃料燃烧不全,出现积碳后果更严重。最佳热值依然是做到和国标汽油持平,成本问题:已知甲醇市场价格是成品汽油的三分之一，约等于25-30%,显然,甲醇比例越高,成本越低,但甲醇热值只有汽油50%,甲醇比例越高,热值越低,油耗越大,甲醇比例低,成本高,市场竞争力不佳,投资失败概率高,M15已有失败的例证。甲醇比例高,成本低,优势显著,但难度在于解次“油耗”,已知在同一发明人的20121053559专利中,已经就解决“油耗”原理阐述,但是其中的原料轻油“石脑油”作为乙烯裂解原料,供不应求,采购困难,或者运输距离太远,造成成本增加,对于南方缺油地区,更是显著。实际运作中,较高的运输成本制约了发展。
发明内容
本发明的目的是为克服现有技术的不足，提供一种汽车用低油耗费托合成粗液蜡醇醚燃料。这种醇醚燃料成本低，油耗低。
实现本发明目的的技术方案是：
一种汽车用低油耗费托合成粗液蜡醇醚燃料，所述醇醚燃料由以下重量百分比的原料制成：变性甲醇35-45%、轻芳烃10-15%、200#溶剂油15-20%、费托合成石脑油25-35%。
所述变性甲醇由以下质量份的原料混合制成：甲醇90份，添加剂10份。
所述添加剂以下质量份的原料混合制成：丙醇20份，乙酸乙酯10份，丁酸丁酯20份，司盘10份，碳酸二甲酯10份，异丙醚20份，二甲醚10份，偏二甲肼0.5份，聚异丁烯丁二酰亚胺0.5份。
上述汽车用低油耗费托合成粗液蜡醇醚燃料的制备方法，所述醇醚燃料制备方法的制备过程为：在常温常压下按重量百分比加入变性甲醇35-45%、轻芳烃10-15%、200#溶剂油15-20%、费托合成石脑油30-35%到容器中混合，所得的混合物即为醇醚燃料，所得醇醚燃料的相对密度为076-0.77，辛烷值在93-100之间可调。
使用时，本技术方案的产品可与国标汽油以任意比例混合使用，也可单独作为车用燃料使用。
这种醇醚燃料成本低，油耗低。
