Oxidation of pyrite catalyst under air were investigated by of XRD and weight change. Synthetic pyrite was oxidized to szomolnokite FeSO_4・H_2O as one of ferrous sulfates even at room temperature. It suggests that iron and sulfur atoms in the strict pyrite structure were moved and rearraged even at room temperature. Activities of pyrite to 1-methylnaphthalene (1-MN) and 1-[4-(2-phenylethyl) benzyl] naphthalene (PEBN) hydroconversion were decreased by the oxidation under air. The low active pyrites oxidized was reactivated by enough sulfur addition to the reaction system.
