Abstract
The properties of catalysts used in the synthesis of hydrocarbons from CO and H/sub 2/ are determined to a significant degree by the carriers used in their preparation. This paper deals with a study of the effect of the type of carrier on the properties of cobalt-based catalysts in the synthesis of aliphatic hydrocarbons from CO and H/sub 2/. Co catalysts that are active in the synthesis of hydrocarbons from CO and H/sub 2/ are those on which the adsorption of H/sub 2/ exceeds 3.10/sup -2/ mmole/g Co and the adsorptin of carbon monoxide exceeds 7.10/sup -2/ mmole/g Co. Carbon monoxide and hydrogen are adsorbed on active catalysts in weakly bound forms. A mechanism is proposed for the formatin of an active center and the adsorption of carbon monoxide on Co-catalysts which includes the appearance of a partial positive charge on the cobalt atom.
