摘要

PATENT IFP Energies nouvelles And ENI SpA COBALT-BASED CATALYST ON A SILICA-ALUMINA SUPPORT FOR FISCHER- TROPSCH SYNTHESIS Sylvie MAURY, Christelle LEGENS, Loic SORBIER, Fabrice DIEHL, Joseph LOPEZ and Lars FISCHER ABSTRACT The present invention concerns a catalyst for carrying out hydrocarbon synthesis starting from a mixture comprising carbon monoxide and hydrogen, the active phase of which comprises at least one metal from group VIII deposited on a support formed by at least one oxide, in which said metal from group VIII is selected from the group constituted by cobalt, nickel, ruthenium or iron, and in which said catalyst has an atomic ratio (Co/Al)not ground/(Co/Al)ground, measured by X-ray photo- emission spectroscopy, in the range 1 to 12. The invention also concerns the catalyst preparation process and its use.
