Process for the Preparation of Catalyst Components for the Polymerization of Olefins
22 Jul 20
A process for the preparation of a solid catalyst component for the polymerization of CH2═CHR olefins, wherein R is hydrogen or hydrocarbyl radical with 1-12 carbon atoms, made from or containing a Ti compound on a Mg chloride based support, including the steps of (a) reacting a Mg based compound with a liquid medium made from or containing a Ti compound, at a temperature ranging from 0 to 150° C., thereby yielding solid particles; and (b) suspending the solid particles coming from step (a) in a liquid medium made from or containing hydrocarbons at a temperature ranging from 10 to 100° C., wherein step (a) or (b) is carried out in the presence of 0.2 to 20.0% by weight, with respect to the amount of Mg compound, of particles of a solid compound containing more than 50% by weight of SiO2 units and having average particle size from 1 to 100 μm.

A method for cleaning a metal surface of a metal component of an industrial plant is disclosed comprising measuring the electrical resistance RA1 of a metal component over a cleaned area of the metal surface with a resistance meter, comparing the electrical resistance RA1 measured with a pre-determined electrical resistance value RDET, assessing whether RA1 is greater, smaller or equal to RDET, and repeating cleaning if the electrical resistance RA1 measured is greater than RDET, or terminating cleaning of the surface area of the metal component if RA1 is smaller than or identical to RDET.
