摘 要:乙醇作为化石燃料的替代品,对于能源需求日趋紧张的中国来说具有非常重要的意义。然而,农作物乙醇作为燃料其生命周期、经济效益及环境效益如何将直接影响其推广使用。文章就农作物乙醇作为燃料的综合效益进行了全面分析,得出了除甜高粱外多数农作物作为燃料乙醇原料具有较低的能效转换率之结论。而且在目前情况下,由于生产成本较高,所产生的经济效益也较差。但其对于解缓能源紧张问题、提高农民收入、促进人员就业具有良好的社会效益,同时对机动车辆的废气污染排放有所改善。As the substitute fuel of petroleum, grain alcohol is significant to China regarding its daily intensive need of energy. However, the popularized usage of grain alcohol as fuel is directly affected by the grain lifecycle, economic benefit and environmental benefit. After completly analyzing the benefits of grain alcohol as fuel, it is concluded that most grain except broomcorn has a comparatively lower conversion rate of alcohol. In addition, the economic benefit is relatively low comparing its high production cost under the current condition. However, it has an excellent social benefit of reducing energy shortage, improving farmer's income and increasing employment. Besides, it helps reduce gas pollution caused by motor vehicles.
