Description

一种提升动力的甲醇汽油添加剂
技术领域
本发明属于甲醇替代车用燃料技术领域，涉及甲醇汽油添加剂，特别是一种提升动力的甲醇汽油添加剂。
背景技术
甲醇燃料是利用工业甲醇或燃料甲醇,加变性醇添加剂,与现有国标汽柴油(或组分油),按一定体积(或重量比)经严格科学工艺调配制成的一种新型清洁燃料.可替代汽柴油,用于各种机动车,锅灶炉使用.生产甲醇的原料主要是煤,天然气,煤层气,焦炉气等,特别是利用高硫劣质煤和焦炉气生产甲醇,既可提高资源综合利用又可减少环境污染.发展煤制甲醇燃料,补充和部分替代石油燃料,是缓解我国能源紧张局势,提高资源综合利用,保护生态环境的一条有效捷径。
根据国家发改委颁布的能源可代替战略政策，以及甲醇汽油标准的陆续制订，使甲醇汽油进一步合法化，促使人们开始试验醇类汽油的各种添加剂。但是在技术上，制约甲醇汽油的最大难题是甲醇热值低，影响汽车发动机的功率输出，这就限制了甲醇的高比例掺入。甲醇汽油将国标汽油(93#、97#等)、甲醇、添加剂按一定的体积(质量)比经过严格的流程调配而成的一种新型环保燃料甲醇与汽油的混合物。也包括甲醇、乙醇、正丙醇、正丁醇和异丙醇的混合醇等与汽油的混合物。
