ABSTRACT:
Hydrotalcite-like clays, catalysts derived therefrom, and methods of hydrocarbon reforming using the catalyst are disclosed. The hydrotalcite-like clays, which may be calcined to form the catalyst, have the formula [M.sup.2+.sub.(1-x) M.sup.3+.sub.x (OH).sub.2 ].sup.x+ (A.sup.n-.sub.x
).mH.sub.2 O at an elevated temperature for a time sufficient to decompose A and to dehydrate said compound, wherein M.sup.2+ comprises at least two species of metal ions having a valence of 2+ selected from the group consisting of Cu.sup.2+, Zn.sup.2+, Ni.sup.2+, and Mg.sup.2+, provided that if M.sup.2+ comprises Mg.sup.2+ at least one of Zn.sup.2+ and Ni.sup.2+ is also present, wherein the atomic ratio of the total of Zn.sup.2+ and Mg.sup.2+ to the total of Cu.sup.2+ and Ni.sup.2+ is up to about 9, inclusive, wherein the total of Zn.sup.2+ and Mg.sup.2+ comprises at least about 5 wt. % of said M.sup.2+ metals; M.sup.3+ is at least one metal ion having a valence of 3+ selected from the group consisting of Al.sup.3+, Fe.sup.3+, Cr.sup.3+, La.sup.3+, Ce.sup.3+, and mixtures thereof; x is a number in the range of about 0.1 to about 0.5, inclusive; A is an anion having a charge of -n; n is an integer in the range of 1 to 6, inclusive; and, m is zero or a positive number.
