ABSTRACT:
Metal-containing zeolitic catalysts, for use in hydrocarbon conversion processes, are prepared by a process which comprises exposing a zeolitic base material, optionally after introduction of metal ions, to adsorb thereon ammonia or a gaseous lower amine, followed by contacting the zeolitic base material containing adsorbed ammonia or amine with an aqueous solution of a salt of the desired metal with a strong acid at a temperature at which adsorbed ammonia or amine is released.
