This study focuses on the hydrogenation of model lignin bio-oil components over ruthenium and platinum catalysts synthesized from a porous aromatic framework, namely PAF-30. This PAF represents a polymeric support with developed porosity and high chemical and thermal stability. The effects of the guaiacol concentration, process temperature, and reaction time on the product composition were identified in the catalytic hydrogenation of guaiacol as a common component of lignin bio-oil. Various guaiacol derivatives were hydrogenated, and the hydrogenate composition was investigated. It was demonstrated that, within one hour at 250°C and a hydrogen pressure of 3 MPa, guaiacol can be hydrogenated exhaustively into 2-methoxycyclohexanol (64%) and cyclohexanol (64%) over the ruthenium catalyst and into a mixture of various hydrogenation products over the platinum catalyst.
