In this study mesoporous zeolite Y (USY-F-AT) was prepared by fluorine–alkaline combined treatment method. The properties of USY-F-AT were characterized by XRD, N2 physisorption, NH3-TPD, XPS, and TEM. USY-F-AT provided greater mesopore volume and surface area than conventional USY. NH3-TPD showed the USY-F-AT has many more acid sites and stronger acid strength compared with USY. Ni and Mo were impregnated into USY and USY-F-AT to form catalysts NiMo/(Al2O3 + USY) and NiMo/(Al2O3 + USY-F-AT), respectively. The hydrogenation activity and cracking ability of catalysts NiMo/(Al2O3 + USY) and NiMo/(Al2O3 + USY-F-AT) were studied by hydrocracking reaction using naphthalene as model compound. The results showed that catalyst NiMo/(Al2O3 + USY-F-AT) exhibited similar hydrogenation activity but much higher ring-opening ability in comparison with catalyst NiMo/(Al2O3 + USY).

氟碱处理萘加氢裂化反应制备介孔沸石Y
在这项研究中，中孔沸石Y（USY-F-AT）是通过氟-碱联合处理方法制备的。USY-F-AT的性能通过XRD，N 2物理吸附，NH 3 -TPD，XPS和TEM表征。与传统的USY相比，USY-F-AT提供了更大的中孔体积和表面积。NH 3 -TPD表明，与USY相比，USY-F-AT具有更多的酸位和更强的酸强度。Ni和Mo分别浸渍在USY和USY-F-AT中以形成催化剂NiMo /（Al 2 O 3 + USY）和NiMo /（Al 2 O 3 + USY-F-AT）。NiMo /（Al 2 O 3 + USY）和NiMo /（Al以萘为模型化合物，通过加氢裂化反应研究了2 O 3 + USY-F-AT）。结果表明，催化剂的NiMo /（铝2 ö 3 + USY-F-AT）表现出类似的加氢活性，但更高的开环的能力与催化剂的NiMo /（比较的Al 2 ö 3 + USY）。
