摘要: The decomposition of lignin was examined in supercritical water with and without phenol at 673 K. In the absence phenol, yield tetrahydrofuran (THF)-insoluble (TIS) products decreased molecular weight distribution THF-soluble (TS) shifted toward lower weights as density increased. increase enhanced conversion. presence TIS TS than those phenol. Some alkylphenols were obtained only phenols, because reaction products. These results show that reactive sites occurred suppressed cross-linking reactions among large fragments. This promoted to lower-molecular-weight compounds.
