Embodiment 1

[0057] Embodiment 1: Preparation of magnesium chloride / alcohol adduct particles

[0058] Take the following steps:

[0059] (1), the preparation of magnesium chloride / alcohol adduct melt: in the 150L reactor with stirring, 10kg anhydrous magnesium chloride and 12.6kg ethanol are added in the white oil that 60L viscosity is 30 centipoise (20 ℃), in The reaction was carried out at 125°C for 2 hours. Then transfer the mixture of molten adduct and white oil to the medium of methyl silicone oil which has been preheated to 125°C; the viscosity of the methyl silicone oil is 300 centipoise (20°C), and the amount of methyl silicone oil is 120L ; Stir at a speed of 200 rpm for 10 to 30 minutes.

[0060] (2) Dispersion: the above-mentioned mixed solution enters the high-gravity rotating bed from the feed port 1 (as attached figure 1 shown), through the static liquid distributor 2 arranged at the center of the rotor, it is evenly sprayed on the inner edge of the high-speed rotating pac...

Embodiment 2

[0064] Embodiment 2: The operation is the same as in Embodiment 1, except that the rotating speed of the supergravity rotating bed is adjusted to 1200 rpm. The results are shown in Table 1.

Embodiment 3

[0065] Embodiment 3: The operation is the same as in Embodiment 1, except that the rotating speed of the high-gravity rotating bed is adjusted to 2000 rpm. The results are shown in Table 1.

Abstract

A spherical catalyst for the polymerizing reaction of olefin is composed of an active magnesium halide carrier, at least one Ti compound and at least one optional electronic doner. Said carrier is prepared from the molten magnesium halide-alcohol addition compound through rotational dispersing in supergravitational field.

Description

technical field [0001] The present invention relates to a kind of spherical catalyst component and catalyst for olefin polymerization, and it in α-olefin CH 2 = Use in polymerization of CHR and mixtures thereof, wherein R is hydrogen or an alkyl group of 1 to 12 carbon atoms. More specifically, it relates to a spherical catalyst component and catalyst prepared from magnesium halide / alcohol adduct particles prepared by high-gravity rotating bed technology, and the catalyst in alpha-olefin CH 2 = Use in polymerization of CHR and mixtures thereof, wherein R is hydrogen or an alkyl group of 1 to 12 carbon atoms. technical background [0002] Magnesium chloride alcoholate particles are well known as supports in spherical catalysts for the polymerization of olefins, especially propylene. In the disclosed catalyst system, the magnesium chloride alcoholate particles are prepared by methods such as spray drying, spray cooling, high-pressure extrusion or high-speed stirring. [000...
