Abstract:
A method for preparing a catalyst support material, the catalyst support material comprising a mixed oxide consisting essentially of a divalent metal and a trivalent metal in a substantially homogeneous phase, which is a calcination product of a hydrotalcite-like phase calcinated at a temperature of between about 750-1200.degree. C., wherein the divalent metal/trivalent metal molar ratio is greater than or equal to 2;wherein a solution comprising a divalent metal salt and a trivalent metal salt is mixed with a basic aqueous solution, the reaction product recovered from said reaction mixture, said product being washed and dried, and the dried product calcinated at a temperature ranging from between about 750-1200.degree. C.;wherein the basic aqueous solution is a composition of aqueous ammonium hydroxides and carbonates.
