液态甲醇在燃料与化工产业的推广应用

Application of Liquid Methanol in Fuel and Chemical Industry

介绍了甲醇的物化特性和甲醇用作替代汽、柴油燃料的优点(清洁环保、经济性好、动力性好、辛烷值高、安全性好、原料来源丰富)。比较了甲醇与汽、柴油的毒性和安全性,以及用作车用燃料时,甲醇与汽、柴油车的常规排放物和非常规排放物,指出甲醇是比汽油和柴油更清洁的车用燃料。分析了甲醇作为化工原料可生产二甲醚、乙烯、甲醛和各种衍生物。最后推荐了煤炭和煤层气制液态甲醇的综合利用技术路线。

This paper introduces the physical and chemical characteristics of methanol and the advantages of replacing gasoline and diesel fuel with methanol,such as cleanness and environment-friendly,good economic performance,good dynamic performance,high octane number,high security and abundant raw material source. The toxicity and safety of methanol are compared with those of gasoline and diesel,and the regulated emissions and unregulated emissions of methanol-fueled vehicles are compared with those of gas ＆ diesel vehicles.It points out that methanol is cleaner than gasoline and diesel as vehicle fuel.As chemical feedstock, methanol can be used to produce dimethyl ether,ethylene,formaldehyde and various derivatives.And a technical line of comprehensively utilizing coal and coal-bed gas to produce liquid methanol is recommended.
