Abstract

Small amounts of potassium were added to the titania - supported cobalt catalysts in order to produce higher and olefinic hydrocarbons in CO hydrogenation. Titania and potassium played important roles not only for the enhancement of the production of higher and olefinic hydrocarbons, but also for the prevention of the catalyst deactivation by carbon deposits. Titania support induced the so - called SMSI, and potassium seemed to act as an electronic modifier, giving rise to an electron enrichment of the metallic phase.
