Summary:
High densities of Ga, In and Cu cations (Me/Al=1) in MFI zeolites have been obtained via thermal treatment of mechanical mixtures of metal oxides with H-MFI resulting in solid state ion-exchange. Ga and In require an H₂ reducing agent during thermal treatment while Cu requires only an absence of O₂ and undergoes autoreduction during thermal treatment. Using both thermal analysis with MS detection and catalytic testing in a gradientless batch recirculating reactor, the modified catalysts have been shown to be highly reactive towards amines. The desorption features of 1-propanamine with cation containing MFI generally differ from those of pure HMFI zeolite. Propanenitrile, C₂-C₆ alkenes and aromatics appear in the decomposition products. Catalytic experiments have revealed that Ga, In, and Cu zeolitic cations promote dehydrogenation and condensation reactions of propanamine to different extents. Such behavior probably results from Lewis acid interactions of the zeolite cation with the amine.
