1,203,066. Steam reforming catalyst. SOC. CHIMIQUE DE LA GRANDE PAROISSE AZOTE ET PRODUITS CHIMIQUES. 19 Oct., 1967 [20 Oct., 1966; 1 March, 1967], No. 47687/67. Heading B1E. [Also in Division C5] A catalyst composition which has a surface area less than 1 m<SP>2</SP>/gm comprises 5-20% of nickel calculated as nickel oxide chemically combined with a refractory support which comprises a major amount of MgO and less than half that amount of Al 2 O 3 so as to produce a "spinel-type" structure. Preferably the catalyst consists of 5-20% Ni, 50-60% MgO and not more than 20% N 2 O 3 . Additionally it may contain one or more oxides of Fe, Cr, K, Na, Ba, Ti, Zr and Ca. |
