摘　　要：本文提出了以Al-MCM-41为固体硅源实现β沸石合成,并对其性质进行了表征,这种β沸石由于具备微孔沸石高酸度特点外,显著改善了孔结构,因而在大分子裂化上具有改善的效能。A β-zeolite was synthesized and made out of Al-MCM-41 and its characterizations showed its promoted pore structure as well as high acidity, which make it possess modified cracking performance for largr molecule.
