| 摘 要： | A series of aluminasilicate Br?nsted acid catalysts were synthesized with the “silica garden” method, and characterized with XRD, XPS and NH3-TPD technique. Acid center concentration was measured using ionic ex-change method. The catalytic activities for cumene cracking of the silica garden Br?nsted acid catalysts were ob-served and compared to that of zeolite HY and traditional acidic aluminasilicate catalysts. It was found that the 6-coordinate and 4-coordinate aluminum atoms were in silica garden Br?nsted acid catalysts. There were two kinds of acid centers and a little of crystal in silica garden Br?nsted acid catalysts. And it was also found that the crystal increased the acidities of the catalysts. The catalytic activity and strong acid center concentration of the silica garden Br?nsted acid catalysts were between that of zeolite HY and traditional acidic aluminasilicate catalysts.
