ABSTRACT:
A method of producing a Raney type catalyst, the method comprising melting together a Raney metal and aluminium to form an alloy mixture, pouring the mixture through a nozzle, directing a gas jet on to the mixture to form a spray of droplets, which droplets are directed on to a metallic substrate, the substrate material and thickness and latent heat and superheat of the sprayed material upon initial contact with the substrate being such that the temperature is sufficiently high for an exothermic reaction to take place between the alloy mixture and the substrate such that intermetallic bonds are formed therebetween, and subsequently chemically removing at least some of the aluminium from the sprayed material.
