Abstract
Abstract: The activity of Fe-Cu-Mo-U catalysts in the synthesis of higher (C1 to C6) alcohols from synthesis gas has been studied at 8.5 MPa. The catalysts have been prepared by coprecipitation and characterized by BET, X-ray diffraction and scanning electron microscopy. The acyl species is the key intermediate in the linear alcohol chain growth. The quantitative estimates of the concentration of the surface species by temperature-programmed desorption experiments allowed the prediction of the ability of the catalyst to induce alcohol chain growth. The study of the carbon monoxide dissociation gives a good estimate of the overall catalytic activity.
