Hydroconversion of Guaiacol Family Molecules Over Platinum Catalysts Based on Porous Aromatic Frameworks
In this work hydrodeoxygenation of various lignin-derived model compounds and their mixture was studied over platinum catalysts based on porous aromatic frameworks (PAF) doped with Bronsted acid sites. Two catalysts, Pt-PAF-30-SO 3 H(5.0) and Pt-PAF-30-SO 3 H(7.5), with almost identical platinum loa...

H(7.5), with almost identical platinum loading of 5.1 and 4.7 wt. % but different sulfur concentration of 4.46 and 6.96 wt. % respectively, were synthesized using a method that allows to obtain highly uniform distribution of nanoparticles in the porous structure of the support. The HDO reaction pathways of lignin substrates with different structures were discussed, and the influence of the platinum source chosen for the synthesis of the catalyst on the activity and the selectivity of the latter was studied. We have demonstrated high stability of catalyst (for at least a 7 h reaction) and have confirmed the great activity of the Pt-PAF-30-SO

H(7.5) was also tested in the hydrodeoxygenation of a model mixture of aromatic substrates taken in proportions contained in lignin bio-oil. The selectivity to naphthenic hydrocarbons—products of the complete hydrodeoxygenation—was 54%.
