Selective Liquefaction of Lignocellulosic Materials
and Its Ecological Industry Chain
Liquefying lignocelluloses with phenol is important. Lignocellulose, which is
regarded as a homogeneous material in complete liquefaction, is actually inho-
mogeneous. Currently, phenol plays an important role in the liquefaction of
lignocellulose. Liquefaction of lignocellulose with phenol is characterized by the
easy liquefaction of lignin and hemicellulose. In contrast, cellulose is liquefied
with difficulty, retained in the residues, and then discarded. Based on these
features, phenol-selective liquefaction of lignocellulose for multilevel conversion is
proposed. Hemicellulose and lignin can be liquefied as much as possible, whereas
cellulose is retained selectively. Lignin and hemicellulose react with phenol to
