摘要
在水热体系中合成了一系列杂原子ZSM-48(M=B,Ge,Cr,V)型分子筛,并用多种物理化学方法对其比表面、热性能、吸附性及表面酸性等物化性能进行了研究,结果表明,杂原子进入分子筛骨架对其性能具有显著影响。
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.
