Abstract: A Dy-alumino-silicate catalyst, useful for hydrocarbon conversion reactions, is chemically characterized by the empirical formula Mx(A102)x(SiO2)y.(H2O)z, where x, y and z are integers, the ratio x:y being usually from 1.0 to 0.2 and where at least 25% (and preferably more than 40%) of the negative charge associated with the aluminum of the alumino-silicate framework is satisfied by a cation of Dy or a cation of an oxide or a hydroxide of Dy. Preferably, upon ignition analysis the catalyst will evolve from 1 to 6 molecules of water (typically 1.5-2.5molecules) for each atom of Dy in the catalyst. Typically the negative charge associated with the zeolite framework is not completely satisfied by cations containing Dy and the balance of cations necessary for electronic equivalency comprise H or cations of metals, metal oxides or metal hydroxides. The zeolite also contains less than one alkali metal cation for every four atoms of aluminum in the framework. The zeolite can be amorphous, but preferably is at least partially crystalline and can adsorb benzene.
