Process for the purification of auxiliary liquids for the manufacture of polyolefins by purification of the mixtures of saturated aliphatic hydrocarbons resulting from the hydrogeneration of carbon oxide that are applied as auxiliary liquids in the polymerization of olefins, especially ethylene, at pressures of less of 100 atm. And temperatures up to 100ºC with the application of catalysts consisting of mixtures of aluminum alkyl combinations and combinations of metals of the secondary group 4º 6º of the periodic system, especially titanium chlorides, characterized in that said hydrocarbon mixtures are conducted first at temperatures of 230-280º, preferably, from 250-260, together with hydrogen by a hydrogenation catalyst, preferably on a nickel-containing catalyst, then subjecting them to an extreme drying, for example, on fine-grained calcium chloride.
