Complete Chemical Hydrolysis of Cellulose into Fermentable Sugars through Ionic Liquids and Antisolvent Pretreatments

Complete chemical hydrolysis of cellulose into fermentable sugars through ionic liquids and antisolvent pretreatments.

This work describes a relatively simple methodology for efficiently deconstructing cellulose into monomeric glucose, which is more easily transformed into a variety of platform molecules for the production of chemicals and fuels. The approach undertaken herein first involves the dissolution of cellulose in an ionic liquid (IL), followed by a second reconstruction step aided by an antisolvent. T...

Fermentable sugars by chemical hydrolysis of biomass.

Abundant plant biomass has the potential to become a sustainable source of fuels and chemicals. Realizing this potential requires the economical conversion of recalcitrant lignocellulose into useful intermediates, such as sugars. We report a high-yielding chemical process for the hydrolysis of biomass into monosaccharides. Adding water gradually to a chloride ionic liquid-containing catalytic a...

Investigation of the Effects of Ionic Liquids Pretreatments and Enzymatic Hydrolysis of Kempas, Koompassia malaccensis

The aim of this study is to investigate ionic liquids (ILs) pretreatment on kempas composition, structure and enzymatic digestibility. Ground kempas (Koompassia malaccensis) was pretreated with 1-butyl-3-methylimidazolium acetate ([Bmim][OAc]), 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and 1-butyl-3-methylimidazolium trifluoromethansulfonate ([Bmim][OTf]), at 120°C for 6 and 12 h. The cel...

One and Two Stage Autohydrolysis Pretreatments for Enzyme Hydrolysis of Coastal Bermuda Grass to Produce Fermentable Sugars

Coastal Bermuda grass (CBG) is an agricultural residue with considerable potential as a feedstock for lignocellulosic-based ethanol. The treatment of biomass with water at high temperature, termed autohydrolysis, can be used to recover sugars in the filtrate and to improve enzyme digestibility of the pretreated solids. The effect of a twostage autohydrolysis process with respect to total sugar ...
