<p>Hydrogenolysis reaction is one of the important reactions to convert lignin into valuable aromatic chemicals. High-pressure hydrogen atmosphere is usually required for hydrogenolysis reaction, which causes high cost of hydrogen transportation and difficulty in handling. Thus we have focused on "in-situ hydrogenolysis" in which both hydrogen production by decomposition of alcohol solvent and hydrogenolysis of the reactant with the hydrogen produced in-situ occur simultaneously. We performed in-situ hydrogenolysis of benzofuran, which is a model compounds of decomposed lignin, in methanol solvent over Pt/Al2O3 catalyst. It was found that only furan moiety of benzofuran was hydrogenated and aromatic compounds like phenol were selectively obtained.</p>
