The process is a two-part synthesis of the catalyst with the water insoluble components in one part and the water soluble components in the other part. The water insoluble components are co-precipitated to form an intermediate catalyst precursor of a precipitated support incorporating oxides of the metal components. The intermediate catalyst precursor is filtered and washed to remove nitrates. The intermediate catalyst precursor is slurried with the remaining water soluble components. A final catalyst precursor is formed by removing the water and incorporating the water soluble components. This two-part process reduces the amount of nitrates in the final catalyst precursor.

  • Patent number: 6964936
    Abstract: A method of making a catalyst with monolayer or sub-monolayer metal by controlling the wetting characteristics on the support surface and increasing the adhesion between the catalytic metal and an oxide layer. There are two methods that have been demonstrated by experiment and supported by theory. In the first method, which is useful for noble metals as well as others, a negatively-charged species is introduced to the surface of a support in sub-ML coverage. The layer-by-layer growth of metal deposited onto the oxide surface is promoted because the adhesion strength of the metal-oxide interface is increased. This method can also be used to achieve nanoislands of metal upon sub-ML deposition. The negatively-charged species can either be deposited onto the oxide surface or a compound can be deposited that dissociates on, or reacts with, the surface to form the negatively-charged species.

  • Patent number: 6864207
    Abstract: A process for making a polyolefin catalyst component, catalyst and polymer resin is disclosed. Controlling the viscosity of a catalyst synthesis solution with the addition of aluminum alkyl alters the precipitation of the catalyst component from a catalyst synthesis solution. The average particle size of the catalyst component increases with an increased concentration of aluminum alkyl in the synthesis solution. The catalyst component can be produced by a process comprising contacting a magnesium alkyl compound with an alcohol and an aluminum alkyl to form a magnesium dialkoxide. Catalyst components, catalysts, catalyst systems, polyolefin, products made therewith, and methods of forming each are disclosed. The reaction products can be washed with a hydrocarbon solvent to reduce titanium species [Ti] content to less than about 100 mmol/L.
