Process Of Lignocellulosic Biomass Valorization And Biofuel Production Using Distillable Green Solvents
Abstract: A process for biofuel production from biomass comprising spent coffee grounds (SCG) and/or coffee husks (CH) by using protic ionic liquids (ILs) for enzymatic hydrolysis thereof, comprising the steps of: Drying castor stalk (CS) in a vacuum oven at predefined temperature and for a predefined period;Directly drying SCG and/or CH; Adding enzymes and citrate buffer to the biomass comprising SCG and/or CH; Synthesizing at least four different protic ILs, by simple base reactions from the respective acids and base thereof; Pre-treating the bio mass containing SCG and/or CH with protic ILs to obtain a slurry thereof; Adding methanol as anti-solvent in the slurry, for cellulose dissolved therein; Washing the slurry/solids with methanol; Filtering and drying the pre-treated slurry overnight at a predefined temperature, preferably at 70 °C in vacuum oven; andRecovering the filtrate by fractional distillation. The present invention also provides a system for producing biofuel, e.g. ethanol from SCG and CH by using protic ILs.
