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.
