Properties of Co-catalysts applied on a cobalt-aluminum spinel in hydrocarbon synthesis from CO and H/sub 2/
Systems containing MgO and Al/sub 2/O/sub 3/ showed maximum activity for hydrocarbon synthesis from CO and H/sub 2/ among Co-catalysts, where cobalt was applied to metal oxides (groups II-III). When these oxides are heated above 400/sup 0/C cobalt ions penetrate the oxide lattice to form spinel structures. The inclusion of cobalt cations into these spinel structures formed when Co-Al/sub 2/O/sub 3/ and Co-MgO catalysts are heated in air, apparently, affects their properties. In this study catalysts containing cobalt-aluminum spinels are examined as carriers during the synthesis of hydrocarbons from CO and H/sub 2/. 9 references, 2 figures, 5 tables.
