Abstract
Catalyst systems and methods for supporting catalysts and their components, particularly metallocene catalyst components, are provided. The method involves teqhniques for evenly distributing a small volume of catalyst component over and among a porous support material. Such even distribution is thought to result in reduced fouling.
Claims12
A process for producing a supported catalyst said process comprising the steps of:
- (a) forming a spray from a volume of catalyst solution wherein the catalyst solution comprises a metallocene catalyst component;
- and
- (b) contacting the spray with a porous support material while agitating the support material
- wherein the volume of catalyst solution is in the range of from more than one times the total pore volume of the support material to less than that volume of solution required to form a slurry when contacted with the porous support.
