| 20090048099 | Process for Preparing a Support for Olefin Polymerization Catalysts - The invention relates to a process for preparing an essentially spherical support for olefin polymerization catalysts, which comprises the steps: preparation of a hydrogel comprising a cogel of silicon oxide and at least one further metal oxide, if appropriate, washing of the hydrogel until the content of alkali metal ions is less than 0.1% by weight, based on the weight of solids, extraction of the water from the hydrogel until the water content is less than 5% by weight, based on the total content of liquid, and drying of the hydrogel to form a xerogel. According to the invention, the extraction step comprises at least one first extraction with a first organic solvent which is at least partially miscible with water down to a water content of 50% by weight, followed by at least one second extraction with a second organic solvent which is at least partially miscible with water. | 02-19-2009 |
| 20100248950 | METHOD FOR MAKING SILICA SUPPORTED CATALYSTS - A method for making an inorganic oxide supported catalyst involves impregnating an inorganic oxide component with a catalytic metal using an aqueous, acid bath. More specifically, the method involves forming and washing an inorganic oxide component, such as a silica gel or a silica co-gel, for example a silica-zirconia co-gel. The washed inorganic oxide component is then contacted with the acidic bath to effect the impregnation with the catalytic metal, such as cesium, to form an activated inorganic oxide component. Subsequently, the activated component is dried to form the catalyst. The resulting catalysts possess increased surface area, which is beneficial with respect to accessibility and amount of catalytically active sites. | 09-30-2010 |
