A PROCESS FOR PREPARING NORMALLY SOLID HYDROCARBONS WHICH COMPRISES REACTING CARBON MONOXIDE AND WATER, AS SOLE INITIAL REACTANTS, IN THE PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF THE METAL MOLYBDITES AND TUNGSTITES, WHICH ARE METAL SALTS OF AN ACID OF THE FORMULA H2MON, WHEREIN N IS FROM 2 TO 3, INCLUSIVE, AND M IS SELECTED FROM THE GROUP OF MOLYBDENUM AND TUNGSTEN, THE METAL SUBSTITUTED FOR HYDROGEN IN THE SAID FORMULA BEING CHARACTERIZED IN THAT THE IONS THEREOF FORM BY REACTION OF AQUEOUS AMMONIA A COMPOUND SELECTED FROM THE GROUP CONSISTING OF OXIDES AND HYDROXIDES WHICH ARE SOLUBLE IN THE PRESENCE OF EXCESS AQUEOUS AMMONIA, AND OXIDES AND HYDROXIDES WHICH ARE SOLUBLE IN WATER, AT A TEMPERATURE IN THE RANGE OF 152* C. TO 350* C. UNDER A PRESSURE OF AT LEAST 200 ATMOSPHERES AND THEREAFTER SEPARATING THE SAID HYDROCARBONS FROM THE RESULTING MIXTURE.
