摘要

Lignocellulosic biomass such as wood has a polymer structure composed of cellulose and hemicellulose (polysaccharides), and lignin (polyaromatic compound). Thus, biomass should undergo a depolymerization process first to form intermediate feedstock molecules that can be utilized in conversion processes for the production of fuels or chemicals. Biomass hydrolysis extracts sugar monomer units from the biomass selectively while thermal chemical processing such as pyrolysis and catalytic fast pyrolysis(CFP) produce bio-oil, composed of 400 organic compounds and aromatics, respectively. We report here that integration of hydrolysis and pyrolysis process can maximize the mass, energy, and carbon efficiency compared to independent application of each process. Namely, the application of pyrolysis (or CFP) to lignin residue after removal of sugars (xylose and glucose) from maple wood by hydrolysis process was found to be the most efficient route for biomass depolymerization.
