甘蔗生产燃料乙醇的发展现状及前景展望

甘蔗是C4作物,其光能转换效率、光合速率、单位面积生物产量显著高于其他作物,其净能比最高。用甘蔗生产燃料乙醇,成本低。甘蔗是最有潜力的生物能源作物,但是我国发展生物能源必须重视能源甘蔗品种的选育,加强甘蔗燃料乙醇生产工艺的研究与开发。利用甘蔗发展燃料乙醇产业具有广阔的前景。分析了我国利用甘蔗发展可再生生物能源的必要性及可行性。

Present Status & the Prospect of Fuel Ethanol Production by Sugarcane

As a C4 plant,sugarcane is rather high in light energy conversion efficiency, photosynthetic rate and biomass productivity (its net energy rate is the highest).Ethanol production by sugarcane is economically practical. It is believed that sugarcane is a most promising energy crop in China.Accordingly, we must pay more attention to the breeding of new sugarcane species and strengthen the research on and the development of fuel ethanol production techniques by sugarcane. The use of sugarcane to develop fuel ethanol has broad foreground. The necessity and the feasibility of the use of sugarcane as renewable resources in China was analyzed in this paper.
