摘　　要：玉米燃料乙醇是一种化石燃料替代品,其可再生能力是评价其性能优劣的一个重要指标。从热力学的角度建立了基于有效能的玉米燃料乙醇可再生性分析模型,并提出一个考虑自然环境自修复能力及允许扰动程度用于修正可再生性理论值的因子。研究结果表明,目前我国玉米燃料乙醇可再生因子的理论值为-2.14,具有不可再生性。文章最后指出了提高我国玉米燃料乙醇可再生能力的重要途径。The renewability of corn fuel ethanol, which is known as an alternative for fossil fuel, is an important criterion for evaluating its performance. The renewability analysis model of corn fuel ethanol is established based on exergy from the view of thermodynamics, and a new factor is put forward to amend the theoretical value of renewability factor, which considers the self-healing capacity and the disturbance permissibility of natural environment in the paper. It is shown that corn fuel ethanol is non-renewable and its theoretical value of renewability factor is -2.14 in China at present Finally, some important ways are indicated to improve the renewability of corn fuel ethanol in our country.
