William C Behrmann, Kym B Arcuri, Charles H Mauldin: Surface supported cobalt catalysts, process utilizing these catalysts for the preparation of hydrocarbons from synthesis gas and process for the preparation of said catalysts. Exxon Research and Engineering Company, Jay Simon, Estelle C Bakun, August 13, 1996: US05545674 (68 worldwide citation)

A supported particulate cobalt catalyst is formed by dispersing cobalt, alone or with a metal promoter, particularly rhenium, as a thin catalytically active film upon a particulate support, especially a silica or titania support. This catalyst can be used to convert an admixture of carbon monoxide a ...
