• The hydrocracking of tetralin was carried out over supported nickel–tungsten (NiO 3%, WO<SUB>3</SUB> 20%) on silica–alumina, alumina, and silica catalysts at a hydrogen pressure of 100 atm and in the temperature range from 325 to 375 °C. The total conversion of tetralin and the product composition of hydrocracking were measured for the catalysts. The influence of pretreatment of the catalysts with H<SUB>2</SUB> and H<SUB>2</SUB>S on the conversion and product composition was investigated for each catalyst. The hydrocracking of decalin was also carried out under the same conditions. It is found that the hydrocracking of tetralin proceeds along two reaction paths: (A) hydrogenation to decalin followed by conversion to methylperhydroindenes and C<SUB>10</SUB>-naphthenes, (B) isomerization to methylindans followed by cracking to butylbenzene. The selectivity of each reaction path and the catalytic properties are discussed.
