Transition metal-graphite catalysts for production of light hydrocarbons from synthesis gas. Quarterly report, August 1, 1976--October 31, 1976. [C/sub 64/Na; C/sub 8/K; interaction of NaCl or KCl with graphite]
Suitable methods have been established for the preparation of alkali and transition metal-graphite catalysts. These involve thermal treatment in vacuo at 300 to 400/sup 0/C of appropriate graphite-transition metal chloride mixtures to affect intercalation of the metal chloride, followed by reduction with alkali metal in vacuo at 250 to 300/sup 0/C, and subsequent removal of excess alkali metal by distillation. Preliminary catalytic testing of sodium and potassium graphites for the Fischer-Tropsch synthesis at 300/sup 0/C and at atmospheric pressure reveals behavior quite unlike that exhibited by conventional supported transition metal catalysts. Notable differences include a complete absence of carbon dioxide from the reaction product in all cases, and, in the case of potassium graphite, exclusive confinement of product distribution to C/sub 1/--C/sub 3/ paraffins. In addition, a considerable fraction of the carbon monoxide reactant that is admitted to a fresh catalyst sample becomes irreversibly adsorbed in an unreactive form that may inhibit the overall reaction rate.
