Abstract

A catalytic method is disclosed for the valorization of lignin. The method comprises subjecting lignin to a catalyzed hydrothermal conversion reaction, said reaction being conducted in the presence of water at an alkaline pH > 8 and a temperature of 200°C-300°C, under the influence of a noble metal catalyst comprising a carbon support. The same reaction can also be applied to subsequently defunctionalize one or more phenolic compounds, notably guaiacol, so as to produce six-membered cyclic hydrocarbons, such as phenol.
