Abstract:
Disclosed herein are dual catalyst compositions containing an unbridged metallocene compound, a bridged metallocene compound, a chemically-treated solid oxide, and an optional co-catalyst. These catalyst compositions can be used for the oligomerization of propylene to produce an oligomer product. For example, a heavy propylene oligomer can be recovered from the oligomer product, and the heavy propylene oligomer can be characterized by a high flash point and viscosity index, and a low pour point.

Claim (Index 21):
An oligomerization process comprising:\n contacting an olefin feedstock comprising propylene with a catalyst composition comprising:\n (i) catalyst component I comprising an unbridged zirconium or hafnium based metallocene compound containing two cyclopentadienyl groups, two indenyl groups, or a cyclopentadienyl and an indenyl group; \n (ii) catalyst component II comprising a single atom bridged, zirconium or hafnium based metallocene compound containing two cyclopentadienyl groups; \n (iii) a chemically-treated solid oxide; and \n (iv) optionally, a co-catalyst; \n to form an oligomer product under oligomerization conditions; and isolating a heavy propylene oligomer by removing unreacted propylene and at least a portion of light propylene oligomers from the oligomer product using one or more separation steps, wherein the heavy propylene oligomer is characterized by a pour point in a range from about 0 to about \u221255\u00b0 C.
