<p>1278982 Reforming catalysts SOC CHIMIQUE DE LA GRANDE PAROISSE AZOTE ET PRODUITS CHIMIQUES 29 May 1969 [30 May 1968 14 April 1969] 4515/72 Divided out of 1278981 Heading B1E [Also in Division C5] A steam reforming catalyst comprises a diffused solution of 50 to 70% MgO, up to 20% Al 2 O 3 , the catalyst having a surface area of 0.02 to 1m<SP>2</SP>/gm. Additionally the catalyst may contain CuO, Fe 2 O 3 , FeO, CoO, TiO 2 , CaO, BaO, SiO 2 , Cr 2 O 3 and/or ZrO 2 . Examples describe the preparation of (1) a catalyst containing MgO, Al 2 O 3 and CaO together with minor proportions of SiO 2 , Fe 2 O 3 , ZrO 2 , K 2 O, Cr 2 O 3 and Fe 3 O 4 ; and (2) a catalyst containing the same basic trio together with minor proportions of SiO 2 , Fe 2 O 3 , ZrO 2 , CrO 3 and CuO.</p> |
