【Abstract】 A series of heteroatom ZSM-48 molecular sieves have been synthesized from hydrothermal systems, and their physicochemical properties,such as specific surface area, adsorption capacity, thermal property and surface acidity are investigated. The results indicate that the introducing of heteroatoms into framework has remarkable effect on the physicochemical properties of ZSM -48 molecular sieves.更多还原
