✦ Synopsis

The H2 isotherms on graphite, CsFeCIs and ClOFeCI, are identical but when activated, &FeCl, shows higher absorption. This suggests that the metallic Fe produced on activation of CsFeCll in Hz at 375°C is on the surface and is not intercalated. The activated intercalation compound, CsFer&, catalyzes the production of hydrocarbons from CO+ H2 but at a slower rate than on activated mixture of graphite and hydrated ferric oxide-chloride. It also has a smaller area of exposed Fe. Finally, it has been shown that the thermal decomposition of FeC19 to FeCI,+C& in the range ISO-300°C is displaced toward FeC12 in the presence of CO because Cl? is removed to form COC12. However, no Fe is produced by this interaction.
