Lignin-phenol monomers govern the pyrolytic conversion of natural biomass from lignocellulose to products

The effect of the interaction between lignin-phenol monomers and holocellulose in natural biomass on the distribution of pyrolysis products remains unknown. The results of this study showed that the interaction between lignin and holocellulose during the pyrolysis of natural biomass became more pron...
