Abstract
The present invention relates to a new catalyst support material comprising a mixed oxide consisting essentially of a divalent metal and a trivalent metal in a substantially homogeneous phase, the mixed oxide being a calcination product of a hydrotalcite-like phase calcinated at a temperature of about 700-1200° C., wherein the divalent metal/trivalent metal molar ratio is greater than or equal to 2. The invention also relates to a process of preparing the support. The invention further provides a catalyst for dehydrogenation which includes a transition metal selected from the first row of transition metals of the periodic table and/or a Group VIII metal impregnated on the new catalyst support material. The invention also provides a process for dehydrogenation of light alkanes using the catalyst.
