A content of the nickel in the alloy granules may be within a range of about 43 wt% to about 60 wt%. The alloy granules may have effective diameters within a range of about 1 mm to about 10 mm. The catalyst may have an attrition value of less than about 7.0%.
A phthalate-free procatalyst composition is disclosed for olefin polymerization that exhibits excellent polymerization activity and response to hydrogen, and can produce a polyolefin exhibiting high stereoregularity, high melt flow rate, and desirable molecular weight distribution. The method for producing the procatalyst composition includes reaction of a magnesium support precursor with a tetravalent titanium halide and a combination of different internal electron donors. The first internal electron donor may comprise one or more substituted phenylene aromatic diester and the second internal electron donor may comprise a polyether, preferably a 1,3-diether. In one embodiment, the support precursor comprises a spherical spray crystalized MgCI2-EtOH adduct.
A process comprising polymerizing olefin monomers and optionally comonomers in a first reactor vessel, thereby forming a raw product stream comprising polymerized solids, unreacted monomer and optionally comonomer, the polymerized solids comprising olefin polymer, volatile organic compounds (VOC) and catalyst system. Then the polymerized solids are contacted with a catalyst poison selected from carbon monoxide, carbon dioxide, oxygen, water, alcohols, amines, or mixtures thereof, thereby forming a passivated stream. The passivated stream is maintained in an agitated state within a second reactor. The passivated stream within the second reactor is then contacted with a circulating gas comprising unreacted monomer for a residence time, thereby reducing the concentration of VOC in the polymerized solids by at least 10 wt% compared to the level before entering the second reactor, thereby forming a purified olefin polymer solids stream.

CATALYST SYSTEM FOR THE PRODUCTION OF POLYOLEFINS AND METHOD OF MAKING AND USING SAME
Catalyst systems for polymerization of mixtures comprising an olefin include a selectivity control agent comprising at least one silicon-containing compound containing at least one C1-C10 alkoxy group bonded to a silicon atom and an amount of one or more agent compounds. The agent compound comprises C2-C13 mono- or polycarboxylic esters of aliphatic C2-C7 carboxylic acids and inertly substituted derivatives thereof. One or more polymerization catalysts may also be present. A polymerization process includes contacting an olefin or a mixture of the olefin and one or more copolymerizable comonomers under polymerization conditions with the catalyst composition.
A polymerization process includes contacting an olefin or a mixture of the olefin and one or more copolymerizable comonomers under polymerization conditions with a catalyst composition and forming a polymer with a total ash content of less than 15 ppm. The catalyst composition includes one or more polymerization catalysts; and a mixed external electron donor comprising a selectivity control agent comprising at least one silicon-containing compound containing at least one C1-C10 alkoxy group bonded to a silicon atom.
A process for preparing a peptized alumina having increased solids and acid contents and a decreased water content. The process comprisesg mixing a boehmite or pseudoboehmite alumina and acid with a high intensity, high energy mixer at a ratio of 0.16 to 0.65 moles acid/moles alumina for a time period sufficient to form a substantially free-flowing solid particulate having a solids content of 45 to 65 wt%. When used in catalyst manufacture, peptized alumina produced by the process provides an increased rate in catalyst production and decreased costs due to high solids concentration and the presence of less water to be evaporated.
