Abstract:

Realumination of dealuminated Hβ, prepared by calcination in air and /or by leaching in HCl solution has been studied by Infrared Spectroscopy. The result shows that the majority of the aluminium defect sites, produced by calcination in air, could be subsequently reinserted by aluminium in the framework under mild condition of alumination, while reinsertion of Al in the defect sites of Hβ framework created by acid leaching was difficult under the same realumination condition.

Key words: Zeolite β, Alumination, IR spectrum
