| Abstract: | The specific surface and the porosity of silicate supports (SiO2, ZrO2 · SiO2, CoO · SiO2) were determined. The adsorption properties and the reducing ability of the catalysts containing 10 % Co were studied. The spectra of the thermo-programmed desorption of CO below 250°C possess two signals typical of the adsorption of the catalyst on the oxide and metal phases. The formation of liquid hydrocarbons from CO and H2 is assumed to proceed at surface bifunctional centers.Translated fromIzvestiya Akademii Nauk.
