Abstract
1514336 Charging polymerization catalyst VEBA-CHEMIE AG 21 July 1975 [27 July 1974] 30436/75 Headings B1F and B1X [Also in Division C3] A method for the continuous dosed introduction of pulverulent olefin polymerization catalyst comprising compounds of the transition metals of IVth - VIth sub groups into a reactor 6 operating up to 100 bar, comprises conveying the catalyst from a vessel 1 in which it is housed under a protective gas, through a dosing unit 2 into a tank 3 containing suspension medium in the absence of a gaseous pressure gradient between vessel 1 and tank 3, and transporting the resulting suspension into the reactor by pressure boost pump at a rate such that the dwell time of the catalyst in the suspension medium is from 10-300 seconds.
