Study on a multi-product symbiosis scheme of fuel ethanol production from cellulosic-based biomass

Cellulosic-based biomass will be used more in the future to produce fuel ethanol for renewable energy development throughout the world.Based on the research object of biomass corn stalk,a recycling process of by-products,produced using cellulosic-based biomass to produce fuel ethanol,is studied by applying the principles of systems engineering and eco-industry in this paper.Through the use of main by-products,a multi-product symbiotic scheme is mapped out,at the same time the technology,economy,environment and market are considered to utilize carbon dioxide,pretreatment liquid,lignin and distillery waste in using corn stalk to produce fuel ethanol.The integration of energy and water in the multi-product symbiotic scheme is analyzed.The preventive measures against the ecological environmental risks are analyzed too.
