Description

一种醇基液体燃料及其添加剂
技术领域
本发明属于民用醇基液体燃料领域，具体涉及一种新型醇基液体燃料及其添加剂。
背景技术
目前的醇基液体燃料大多数是甲醇为主也有加入少量的工业乙醇，混配的醇基液体燃料由于甲醇热值较低，燃料消耗量从理论上讲是燃用柴油的1.8倍以上，但由于醇基燃料燃烧完全，再配置效率高的燃烧设备，使其热效率提高，甲醇燃料消耗量与柴油比完全可以达到柴油的1.3倍。所以在众多的清洁燃料中，醇基燃料由于具有来源广泛、丰富、排放低、燃烧彻底清洁卫生、节能环保深受用户的欢迎。
目前，醇基液体燃料市场混乱，缺乏各个环节的统一质量标准和使用规范；甚至一些生产经营者在醇基燃料中添加氧化剂，造成安全隐患或不应有的事故。有些醇基液体产品燃烧不充分，污染环境且增加燃烧成本。
