摘要： Method for activation of chromium containing catalyst precursor for polymerization and improved polymerization catalyst resulting The instant invention relates to an activation of a polymerization catalyst precursor by heat treatment comprising a support material and a catalyst precursor deposited thereon in a fluidized bed activator and to the use of the activated polymerization catalyst in the manufacture of polyolefins. The Method is performed in a cylindrical activator (1) arranged vertically comprising tubular activator walls, a fluidization gas inlet (2) near the bottom, a fluidization gas outlet (3) near the top and a heat exchange jacket (4) outside the tubular activator walls, wherein the heating jacket covers the complete outer surface of the walls of the activator. The catalyst prepared by that method is improved with respect to its minor content of impurities and causes less interruptions during gas-phase polymerization or slurry polymerization either in stirred vessel or loop.

摘要： The instant invention relates to an activation of a polymerization catalyst precursor by heat treatment comprising a support material and a catalyst precursor deposited thereon in a fluidized bed activator and to the use of the activated polymerization catalyst in the manufacture of polyolefins. The activation involves heat treatment in the presence of oxygen. After that activation the oxygen in the activator is replaced by inert gas via flushing until the fluidization gas emerging from the activator comprises oxygen in a maximum amount of up to 5 ppm. The catalyst prepared by that method is improved with respect to prevent reactor fouling during gas-phase polymerization or slurry polymerization either in stirred vessel or loop.

摘要： The invention relates to a method for producing supported chrome catalysts for the polymerisation of olefins by loading a xerogel carrier with chrome by mixing the xerogel carrier with a volume of a 0.025 to 15 wt. % solution of a chrome compound or with a volume of a 0.025 to 7.8 wt. % Cr-containing solution which is essentially converted into a chromium(VI) compound when said solution is heated in a water-free flow of gas under oxidising conditions to temperatures ranging from 300 to 1,100 °C over a period of 10 to 1,000 min, whereby the xerogel carrier is mixed in a solvent which contains not more than 20 wt. % water. The xerogel is loaded by subsequently vaporising the solvent, whereby the volume of the chromium salt solution used is smaller than the pore volume of the xerogel carrier.
