Bimetallic catalysts with higher activity |
| abstract |
The present invention relates to a method for producing a bimetallic catalyst. The method comprises the steps of providing a supported non-metallocene catalyst, contacting a slurry of the supported non-metallocene catalyst in a nonpolar hydrocarbon with a solution of the metallocene compound and alumoxane, and drying the contact product Obtaining a supported bimetallic catalyst. The supported non-metallocene catalyst dehydrates the particulate support material at a temperature above 600 ° C., produces a slurry of dehydrated support in nonpolar hydrocarbons, and contacts the slurry with an organic magnesium compound and an alcohol, resulting slurry Is prepared by contacting a non-metallocene compound in a Group 4 or Group 5 transition metal and drying the contact product to obtain a supported non-metallocene catalyst as a free flowing powder. Bimetallic catalysts exhibit a relatively increased activity compared to catalysts prepared using support materials dehydrated at low temperatures. |
