VERFAHREN ZUR HERSTELLUNG NICKEL UND ALUMINIUM ENTHALTENDER KATALYSATOREN UND DEREN VERWENDUNG

摘要

The compound Ni6Al2(OH)16. CO3. 4H2O is isolated from aqueous solution. The catalyst is obtained from this compound by drying, calcination and subsequent reduction in a stream of hydrogen, whilst maintaining very specific temperature gradients between the drying stage and the calcination stage. A process for the manufacture of gases containing methane from hydrocarbons by steam cracking, in which the abovementioned catalyst is employed, is also described.
