摘要 酒精经深加工 ,作为可再生资源用作汽车燃料 ,可缓解人类赖以生存的资源短缺。我国2000年车用汽油耗量5000万吨 ,按10 %添加比例 ,年需500万吨无水乙醇 ,市场前景广阔。恒沸精馏工艺生产无水乙醇 ,产量大 ,质量好 ,消耗低 ,机械化程度高。生产实践证明 ,每生产100L无水乙醇消耗蒸汽83kg,环己烷0.025 % ,酒精损失为0.1 % ,吨无水乙醇耗电19kw·h左右。(一平) Alcohol after deep-processing is regarded as regenerated resources and used as vehicle fuel which could settle the problem of scarcity of resources. The vehicle gasoline consumption in year 2000 in China has reached 50 million tons, calculated by 10% addition proportion, we do need 5 million tons of anhydrous alcohol annually which means bright market prospects. The appliction of constant boiling and rectification in the production of anhydrous alcohol has advantages of more yield and better quality and lower consumption and higher mechanization levels. And the practice also indicated that the production of every 100L anhydrous alcohol would consume 83kg steam and 0.025% hexamethylene and about 19kw.h electronic energy with 0.1% alcoholic loss.
