Abstract:
A monolithic carrier provided with longitudinal holes or passages is immersed in a mixed solution containing a salt of the platinum group metal and a sol of the alumina type as additional material. After immersion the coated carrier is dried in hot air and the salt is reduced in a stream of hydrogen at an elevated temperature to a metal to give a catalyst on the monolithic carrier. The sol may be converted into a gel before the reduction step.
Abstract:
A catalyst composition consisting of oxides of nickel, chromium and zirconium which are carried on a carrier of a monolithic structure or on tablets, pellets or the like. The catalyst composition may further comprise one of manganese, zinc, copper and iron oxides so as to provide further increased activity and durability. A method of producing the catalyst of the type described above is provided, in which the metal oxides are formed from the corresponding metal salts or metal hydroxides by sintering.
