1511789 Shaped reforming catalyst particles A.P.C. (AZOTE ET PRODUITS CHIMIQUES) CATALYSTS & CHEMICALS EUROPE 22 Oct 1976 [22 Oct 1975] 44023/76 Heading B1E [Also in Division C5] A catalyst for reforming of hydrocarbons comprises (i) a support containing at least 98% wt. of alumina, having the shape of a hollow cylinder containing at least four partitions '6' each extending radially from the longitudinal axis of the cylinder to its inner surface, the water porosity of the support before impregnation being 0.08-0.20 cc/g, and (ii) 4-15% nickel oxide, deposited by impregnation on the support. The support may have five internal partitions (Fig. 2 not shown) or more, preferably spaced equiangularly. The support may contain up to 2% wt. of oxides of Ti, Mn, Be, Zr. Th, Ba, Ca, Na, K or Si, or mixtures thereof. It may be formed by addition of alumina, preferably alpha-alumina, and optionally, the other oxide ingredients to an alumina gel; forming into the correct consistency, e.g. by addition of water, organic binders or thermoplastic material; extruding; and calcining. The Examples relate to the use of supports containing, in addition to alumina, sodium and potassium oxides alone or together with oxides of manganese and titanium. |
