 1449a.    HOFER, L. J. E., ANDERSON, R. B., PEEBLES, W. C., AND STEIN, K.  Chloride Poisoning of Iron-Copper Fischer-Tropsch Catalysts.  Jour. Phys. and Colloid Chem., vol. 55, 1951, pp. 1,201-1,206; Chem. Abs., vol. 46, 1952, p. 233.

         Catalysts prepared from ferrous, ferric, and cupric ion solutions are active only when they contain sizable amounts of Fe**.  The β-Fe₂O₃·H₂O catalysts contain up to 0.92% Cl, the poisoning effect of which accounts for the inactivity of this catalyst.  Activity is not affected by the presence of Cu.
