  Verfahren zur Herstellung von Nickel in Form von porösen Körnern oder Stücken   beliebiger Grösse.   



   Es ist bekannt, dass man bei der   Reduktion   von Nickeloxyd oder anderen Nickelverbindungen metallisches Nickel erhält. Letzteres wird nach der bisherigen Darstellungsart in fein verteilter Form als feines Pulver gewonnen, das schwierig zu handhaben ist und 
 EMI1.1 
 förmiges Nickelkarbonyl überführt und aus letzterem das Nickel auf in   Bewegung erhaltenem   Nickelschrot oder dgl. niederschlägt.

   Auch pflegte man Nickeloxyd oder eine Nickelverbindung mit Sirup oder dgl. zu vermengen und das Gemenge zu Kuchen zusammenzubacken, welche 
 EMI1.2 
 und dann in einer   Atmosphäre   von Wasserstoff, Stickstoff oder einem anderen, auf Nickel nicht einwirkenden Gase auf eine Temperatur erhitzt, die wenig unter seinem Schmelz-

   ' der einem () fen   aufgelegt werden und wenn dann auf diese Art die geeignete Temperatur   zur     Reduktion   der   Nickelverbindung in   bekannter Weise erreicht worden ist, z.   B.   etwa 400  C, kann man Wasserstoff oder Stickstoff einlassen und die Temperatur auf die erforderliche Höhe steigern, um das teigartige zusammenhängende Metall zu erzeugen.

   In vorstehend   angegebener Weise bereitetes Nickel   ist in   hohem   Grade aktiv und eignet sich zu allen Verwendungszwecken, bei welchen die   katalytischen   Eigenschaften dieses Metalles inBetrachtkommen.

  Process for the production of nickel in the form of porous grains or pieces of any size.



   It is known that metallic nickel is obtained from the reduction of nickel oxide or other nickel compounds. The latter is obtained according to the previous type of representation in finely divided form as a fine powder, which is difficult to handle and
 EMI1.1
 formed nickel carbonyl and from the latter the nickel is deposited on nickel shot or the like that is kept in motion.

   It was also customary to mix nickel oxide or a nickel compound with syrup or the like and bake the mixture into cakes, which

 and then heated in an atmosphere of hydrogen, nitrogen, or some other gas not acting on nickel, to a temperature a little below its melting point.
 EMI1.3
   'the one () fen and when the appropriate temperature for reducing the nickel compound has been reached in a known manner in this way, z. B. about 400 C, you can let in hydrogen or nitrogen and raise the temperature to the required level to produce the dough-like coherent metal.

   Nickel prepared in the above manner is highly active and suitable for all uses in which the catalytic properties of this metal are taken into account.
