abstract={The modifications of NaY zeolites with different SiO<SUB>2</SUB>/Al<SUB>2</SUB>O<SUB>3</SUB> ratio were carried out, the results revealed that modified USY zeolites showed some mesopores, as the SiO<SUB>2</SUB>/Al<SUB>2</SUB>O<SUB>3</SUB> ratio of USY increased, the weak acidity strength of USY had little change, medium and strong acidity strength of USY decreased, the weak acidity and medium-strong concentration decreased.The selective ring opening evaluation of tetralin revealed that hydro-upgrading catalyst with different USY zeolites had different tetralin conversion, different yield and selectivity of ROP. The catalyst prepared with USY zeolite modified from NaY with the SiO<SUB>2</SUB>/Al<SUB>2</SUB>O<SUB>3</SUB> ratio of 5.7 showed best hydro-upgrading performance, which had higher tetralin conversion, higher yield and selectivity of ROP. Acidity and Si/Al ratio of USY zeolites both were important factors affecting catalyst performance.},
