Catalytic hydrogenolysis of alkaline lignin with a production of biofuel

Synthesized 5% Pd/Al2O3 and 5% Pd/ATP were used in the hydrogenolysis of lignin in the presence of a solvent of a hydrogen donor, propanol-2, to obtain liquid fuel components. It has been established that the use of Pd-containing alumina-based catalysts makes it possible to obtain phenolic compounds, while in the presence of catalysts based on a polymer matrix from hyperastained polystyrene, the main products are cycloalkanes. In addition, the study of the hydrogenolysis process showed that when using propanol-2 as a solvent, the formation of aromatic compounds is mainly observed, while in the aqueous medium a high yield of phenols is achieved.
