A PROCESS FOR PREPARING HYDROCARBON WAX WHICH COMPRISES INTRODUCING METHANOL INTO A PRESSURE-RESISTANT REACTION VESSEL, HEATING THE SAID METHANOL UNDER SUPERATMOSPHERIC PRESSURE WITHOUT ADDITION OF ANY OTHER REACTANT AT A REACTION TEMPERATURE WITHIN THE RANGE OF 100* TO 350*C. IN THE PRESENCE OF A CATALYST CONTAINING ELEMENTARY COBALT, AT A PRESSURE OF AT LEAST 65 ATMOSPHERES, CONTINUING SAID HEATING UNTIL THE SAID METHANOL IS CONVERTED, AT LEAST IN PART, TO AN ESSENTIALLY HYDROCARBON WAX, AND THEREAFTER SEPARATING THE SAID WAX FROM THE RESULTING MIXTURE.
