The present invention relates to a process for the preparation of hydrocarbons by catalytic reaction of carbon monoxide with hydrogen in which reaction a feed comprising hydrogen and carbon monoxide is contacted at elevated temperature and pressure with a catalyst comprising cobalt and manganese in which catalyst the cobalt/manganese molar ratio is between 14:1 and 7:1 and the GHSV is at least 1600 N1/1/h. Preferably the cobalt/manganese molar ratio is between 13:1 and 9:1 and the GHSV is between 2700 and 25,000 N1/1/h. The reaction is especially carried out in a slurry phase regime.

La présente invention concerne un procédé de préparation d'hydrocarbures par réaction catalytique de monoxyde de carbone et d'hydrogène. Pour réaliser le processus de réaction, on met en présence, à une température et une pression élevées, une charge de départ contenant de l'hydrogène et du monoxyde de carbone, et un catalyseur contenant du cobalt et du manganèse, le rapport molaire du cobalt/manganèse étant compris entre 14:1 et 7:1 et la vitesse spatiale horaire du gaz (GHSV) étant d'au moins 1600 N1/1/h. De préférence, le rapport molaire cobalt/manganèse est compris entre 13:1 et 9:1 et la GHSV est comprise entre 2700 et 25000 N1/1/h. La réaction est réalisée en particulier en régime de phase de suspension.
