The hydrogenolysis reaction of model compounds was discussed in the presence of synthetic pyrite as catalyst under 3MPa of initial hydrogen pressure at 325〜500℃ for 15min. At the lower reaction temperature than 400℃ synthetic pyrite catalyst accelerated C-0 bond cleavage and the formation of benzylphenol and the condensed products such as dibenzylphenol and tribenzylphenol. It was difficult to cleave aliphatic bridged C-C bond such as bibenzyl under this reaction condition.
