Procédé de conversion du gaz de synthèse en présence d'un catalyseur comprenant au moins un élément du groupe VIII dispersé sur un support comprenant de l'alumine modifiée par imprégnation aqueuse de silicate d'ammonium quaternaire et comprenant entre environ 3 %poids et environ 9,5 %poids de silice. Ledit support peut éventuellement comprendre en outre au moins un oxyde choisi dans le groupe constitué par les oxydes de terre rare, les oxydes d'alcalino-terreux et l'oxyde de zirconium. A process is described for converting synthesis gas in the presence of a catalyst comprising at least one group VIII element dispersed on a support comprising alumina modified by aqueous impregnation of quaternary ammonium silicate and comprising in the range of about 3% by weight to about 9.5% by weight of silica. Said support can optionally also comprise at least one oxide selected from the group formed by rare earth oxides, alkaline-earth oxides and zirconium oxide.
