A method is suggested to remove cobalt carbonyls from circulation synthesis gas in Oxo process. For this purpose, circulation synthesis gas is passed through pumice-stone. As a result, the gaseous cobalt hydrocarbonyl contained in synthesis gas transforms into dicobaltoctacarbonyl by reaction

Dicobaltoctacarbonyl is a solid substance at normal temperature. During reaction it adsorbs on pumice. Refined (cobalt-free) circulation gas is returned to the reactor. Since pumice is used in Oxo process as a support for cobalt catalyst, there is no need to regenerate the "spent" pumice, and it can be used for the catalyst preparation.
