摘要: Bioethanol can be produced from lignocellulosic feedstock using a biochemical route involving enzymatic hydrolysis followed by microbial fermentation. During these processes, about 30 to 40% of the biomass is left behind as wet unhydrolyzed solids (UHS), depending on type biomass, enzyme loading, and duration hydrolysis. The UHS mostly composed lignin, bound enzymes, undigested recalcitrant carbohydrates ash. efficient conversion into bio-oil will increase overall efficiency liquid fuels (bioethanol bio-oil) has potential reduce cost biofuel production biomass. In this paper we report results bio-oils via hydrothermal liquefaction (HTL) under varying temperatures (280–350°C) subcritical water conditions. effects K2CO3 supported bimetallic CoMo/Al2O3 catalysts during HTL process were investigated. used in study was after h...
