| Abstract: | This paper investigated various modification methods on Y zeolites, including acid leaching, steam dealuminating and chemical dealuminating such as low temperature reaction with fluorosilicates as well as with oxalic acid. It is desirable in FCC process that modefied Y zeolites have small unit cell demension, low coke formation and higher gasoline yield. |
