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