Abstract

Abstract: The extra-framework aluminum of SDYzeolite has been leached out with Na₂H₂EDTA,H₄EDTA and HCl respectively.The structures,acidities and catalytic properties of these samples have been studied by using chemical analyses,XRD,N₂ adsorption,NH₃-TPD and n-heptane cracking reaction.It is found that Na₂H₂EDTA is a selective extractant which removes only amorphous extra-framework aluminum deposited in the zeolite pores without destroying the framework aluminum,Both the n-heptane cracking activity and nitrogen-resistance properties of SDY-NaE are higher than those of SDY.

Key words: SDY zeolite, Leaching, Extra-framework aluminum, Catalytic cracking
