A few species of ultrastable Y zeolite with homogeneous aluminium distribution were prepared by means of combining hydrothermal roast and adding some A12(SO4)3 into the H2SiF6-NH3 dealumium ized and silicon enriched ultrastable Y zeolite slurry.

• 采用水热焙烧和向H_2SiF_6-NH_3脱铝补硅超稳Y沸石体系中添加适量Al_2(SO_4)_3的方法制备出几种铝分布均匀的超稳Y沸石分子筛。
