燃料乙醇炼制系统优化与碳减排研究进展

Research progress on optimization of fuel ethanol refining system and carbon emission reduction

生物质是丰富可再生的碳源,以糖、淀粉、秸秆纤维素或其他生物质原料高效生产燃料乙醇,可减少化石能源的需求,其中以木质纤维素为原料的第二代燃料乙醇具有广阔的发展前景。与化石能源相比,燃料乙醇具有环保、经济、可再生的优势,但其在生产工艺技术、经济效益和环境影响等方面仍需要深入研究。近年来,通过开展燃料乙醇炼制系统优化及全生命周期分析研究,有力地促进了燃料乙醇技术进步,推动了燃料乙醇碳减排相关研究。文章主要论述了近年来燃料乙醇生产技术的发展,重点对燃料乙醇系统的模拟优化和碳减排研究进展进行了总结,并对燃料乙醇发展趋势进行了展望,以期为燃料乙醇的可持续发展提供参考。

Biomass is a rich and renewable carbon source.The efficient production of fuel ethanol with sugar,starch,straw cellulose or other biomass feedstocks can reduce the demand for fossil energy,among which the second-generation fuel ethanol with lignocellulose as feedstock has broad prospects for development.Compared with fossil energy,fuel ethanol has the advantages of environmental protection,economy and renewable energy,but its production technology,economic benefits and environmental impact still need to be further studied.In recent years,through the optimization of fuel ethanol refining system and the study of the whole life cycle analysis,the progress of fuel ethanol technology has been effectively promoted,and the related research on carbon emission reduction of fuel ethanol has been promoted.This paper mainly discussed the development of fuel ethanol production technology in recent years,focused on the research progress of simulation optimization and carbon emission reduction of fuel ethanol system,and looked forward to the development trend of fuel ethanol,in order to provide reference for the sustainable development of fuel ethanol.
