Abstract
A novel precious metal doped porous metal catalyst is disclosed. The precious metal is present in from 0.01 to 1.5 weight percent and distributed throughout the particles of porous metal to provide a surface to bulk ratio distribution of not greater than 60. The present invention is further directed to a process of forming said doped catalyst and to improved processes of catalytic hydrogenation of organic compounds.
Claims39
A product comprising a porous particulate metal material comprising a porous sponge base metal alloy having a major amount of a metal selected from Ni, Co, Cu, Fe or mixtures thereof, and havinq from about 0.01 to about 1.5 weight percent of a precious transition metal coated on the surface of said base metal alloy and distributed throughout said particulate material to have a S/B ratio of less than 60.
A product comprising a porous particulate metal material comprising a sponge porous base metal alloy having at least about 85 weight percent of a base metal selected from Ni, Co, Cu or Fe or mixtures thereof and further comprising up to 15 weight percent of aluminum, molybdenum, chromium, iron, copper, tin, zirconium, zinc, titanium, vanadium or mixtures thereof, and further having from about 0.01 to about 1.5 weight percent of a precious transition metal coated on the surface of said base metal and distributed throughout said porous particulate material to have a S/B ratio of less than 60.
