Method for the digestion-precipitation of high activity catalysts

摘要

A metal oxide catalyst of high surface area is prepared by dissolving a metal salt in a polar organic solvent, precipitating the metal from solution in a form thermally decomposable to the oxide by means of a precipitating agent which is sparingly soluble in the solution, separating the precipitate, drying and calcining to form the metal oxide. The technique is particularly suitable for the preparation of Group VIIIA metal oxide catalysts which are useful for the conversion of carbon monoxide to hydrocarbons.
