Abstract: The present invention describes a catalyst support, which is used as an inorganic carrier for a Ziegler-Nata catalyst (ZN), using a modified spray cooling method. Such a catalyst support is prepared from alcoholic solutions of (a) an inorganic compound, in which the inorganic compound is a magnesium compound and (b) an inorganic compound and one or more additives. The solutions are prepared at a temperature below 100° C., carried through a nozzle placed inside a reactor, and sprayed into droplets forming a solid precipitate, which is generally spherical, when in contact with an inert hydrocarbon solvent at low temperature. The obtained catalyst support is reacted with a titanium compound, preferably titanium tetrachloride, in order to produce an active catalyst for olefin polymerization.
