Supercritical Water Gasification of Phenol and Benzene as Lignin Biomass Model Compound: Detailed Reaction Pathways and Kinetics

T. L.-K. Yong & Y. Matsumura
The effect of temperature (370–450 °C) and residence time (0.5–100 s) on phenol and benzene decomposition in supercritical water (SCW) at pressure of 25 MPa was investigated. Because of the complexity of the lignin biopolymer, studying simple model compounds such as phenol and benzene is an essential preliminary step in elucidating the primary mechanism of char and gas formation. Based on the deduced mechanism, we proposed reaction pathways for the decomposition of phenol and benzene...
