Abstract

In this paper, a study on direct growth of SAPO (CHA) zeolites on aluminium foamed supports is presented.A preliminary investigation on SAPO-34 and SAPO-44 syntheses was carried out by conventional hydrothermal and microwave route to select appropriate formulations for in situ growth on aluminium foams. Adsorption capacity of coated foams were evaluated by a McBain system and compared to adsorptionisobars of pure zeolites measured by a Chan microbalance. Coated samples showed the typical behaviour of the corresponding zeolite, confirming that the interaction with aluminium support was not detrimental to the zeolite adsorption performances. SAPO-34 coatings grew ten times faster bymicrowaves than by hydrothermal route, while for SAPO-44 the microwave deposition was not feasible for the intense corrosion of aluminium foams.
