Abstract

Abstract: In situ IR studies of benzene adsorbed on different potassium-exchanged degrees of KHβ zeolites were carried out under different conditions.The bands of adsorbed benzene on KHβ zeolites in the range of 2050-1750 cm^-1 were assigned.The KHβ zeolite has basicity only when the ratio of K to AI of KHβ is up to 88.39%, its basicity is stronger and its acidity is weaker.The order of stability ofthe adsorbed benzene species on the samples is O_b^->H_b⁺>K_b⁺>b.

Key words: Absorption, Benzene, Zeolite
