Description

增效减排醇基燃料
技术领域
本发明属于燃料技术领域，特别涉及一种增效减排醇基燃料。
背景技术
随着石油资源的日益枯竭，人们在努力寻找它的代用品。甲醇因其具有洁净、高热值、高效率和容易取得等特点被世界各国作为替代汽、柴油的潜在首选液体燃料。更有些国家已将其作为一种现实的车用液体燃料来使用。国内将甲醇作为柴油代用品已有较多的实例。作为柴油代用品则正处于探索之中。甲醇用作车用发动机燃料存在的主要问题：
一是甲醇燃料的动力性能低于柴油；二是十六烷值低，只有2～3，而柴油机压缩起动时其十六烷值不能小于45；
第三是甲醇对发动机系统的非金属件有溶涨腐蚀作用，而对金属件则存在电位腐蚀问题；
第四是甲醇的粘度系数小，因而其对发动机系统有一定的冲刷作用；
第五是甲醇与柴油相溶性，遇水分层，贮存稳定性差。
此五个问题是目前影响甲醇用作柴油机燃料的主要障碍。目前，利用甲醇作车用发动机燃料，在现有燃料油中添加一定比例的甲醇和其它添加剂，但是甲醇代替量较低，替代效果不强。甲醇燃料添加剂可以保护发动机的燃油系统、进气系统、润滑系统等部位，让发动机发挥持续的、可信赖的性能，通过清除积碳、油泥，可以提升动力，节省燃油，降低噪音，减少环境污染、降低因燃油导致的发动机故障。但现有的甲醇燃料添加剂有些虽能在一定程度上改善燃料在内燃机中的燃烧性能，但会造成内燃机生锈、积碳严重，大大降低内燃机的正常运行，且同样污染环境；有些虽能减少环境污染，但却并不能很好的提高燃料在内燃机中的燃烧效率，造成油耗增加；有些即便能提高燃料在内燃机中的燃烧效率并对环境污染有所改善，但效果也并不是很理想，且使用的原料成本较高、制作工艺较为复杂。因此研究开发一种增效减排醇基燃料变得非常重要。
发明内容

5、本发明的原料协同作用，还具有抗冻作用和消烟作用，能使碳烟颗粒降低到较低水平，也较好改善燃料机超细微粒的排放。
6、本发明的增效减排醇基燃料，经测试，存放至少18个月不分层，不变质；燃料热值较柴油提高700～950大卡/公斤；铜片腐蚀(50℃，3h)为1a级；十六烷值较柴油提高，7～9个单位；尾气中的CO、HC、NOX和颗粒物较使用柴油排放分别降低45～65％、35～65％、43～77％、62～90％，经计算，可节约成本33.2％～39.4％。
