Abstract
The specific surface and the porosity of silicate supports (SiO2, ZrO2 . SiO2, CoO . SiO2) were determined. The adsorption properties and th e reducing ability of the catalysts containing 10 % Co were studied. T he spectra of the thermo-programmed desorption of CO below 250-degrees -C possess two signals typical of the adsorption of the catalyst on th e oxide and metal phases. The formation of liquid hydrocarbons from CO and H-2 is assumed to proceed at surface bifunctional centers.
