ABSTRACT:

Cobalt-graphite intercalate, prepared by reduction of the corresponding CoCl sub 2 -graphite with an aromatic anion-radical, exhibits low to moderate activity for the hydrogenation of carbon monoxide to hydrocarbon products. Compared to a kieselguhr-supported cobalt catalyst, however, the graphite-based material produces substantially less methane (30 to 35% vs. 55 to 60% of all CO converted) and correspondingly more C sub 3+ hydrocarbons (45 to 50% vs. 25 to 30% of all CO converted) at a reaction temperature of 250 exp 0 C. The catalytic activity of cobalt-graphite is markedly dependent on the method of reduction of the CoCl sub 2 -graphite precursor. Reduction of CoCl sub 2 -graphite with sodium borohydride produces a cobalt-graphite intercalate that has much lower activity for carbon monoxide conversion than that prepared by reduction with an anion-radical.
