Title: Catalyst on silica support
IPC: B01J37/02
Filed: 1960-04-28
Abstract: A catalyst is prepared by a process comprising forming a suspension of high purity silica gel powder (of particle size 1-20m  and average particle size 5-15m ) in an aqueous sodium silicate solution such that the powder constitutes 15-25% of total silica, reacting the suspension with aqueous acid giving a silica hydrosol, converting the latter to hydrogel, purifying, drying and calcining the hydrogel to form silica gel particles in which at least 50% of the pore volume consists of pores having a diameter greater than 0,004m , impregnating (at one or more stages in preparation) an active catalytic metal of atomic number 23-82 to constitute 0,1-40% of the composite and heat treating the product.  The catalyst may be in the form of beads made by setting the hydrosol in a water-immiscible organic liquid and drying with superheated steam.  Preferably the powder-included silica particles are impregnated with nickel, especially in the form of an aqueous nitrogenous nickel formate solution.  Such nickel catalysts are suitable for catalytic hydrogenation of fats and oils; the hydrogenation of olive oil and of tallow oil are exemplified.  Details are also given of the preparation of a platinum catalyst, while other catalytically active components mentioned are zinc chloride, iron oxide, vanadium oxide, nickel oxide, silver, rhodium, nickel tungstate and manganese.
