Abstract: The compound Ni5MgAl2(OH)16.CO3.4H2O is precipitated from an aqueous solution containing salts of nickel, magnesium and aluminum with a carbonate or bicarbonate of an alkali metal. After this catalyst precursor has been dried, calcined and reduced with hydrogen a catalyst can be prepared which is suitable for the cracking of hydrocarbons in the presence of steam. In the steam cracking of hydrocarbons the hydrocarbon and the steam may be reacted to form a gas rich in methane in contact with this catalyst at a preheating temperature of less than 300* C.

Abstract: Gases of various origins which contain carbon monoxide and dioxide and hydrogen, for example the gases obtained by steam reforming or the rich gas process, refinery gases or coal gasification gases are methanized on a nickel catalyst. The object of this reaction is to obtain methane or gases which can be substituted for natural gas. To produce the catalyst, the compound Ni6Al2(OH)16.CO3.4H2O is obtained from aqueous solution. The catalyst is obtained from this compound after drying, calcination and subsequent reduction in a stream of hydrogen, whilst maintaining very specific temperature gradients between the drying stage and the calcination stage.
