Title:
POLYALPHAOLEFINS BY OLIGOMERIZATION AND ISOMERIZATION
Document Type and Number:
WIPO Patent Application WO/2012/134688
Kind Code:
A8
Abstract:
A feedstock of one or more C4 to C24 alpha olefins is oligomerized with a metallocene catalyst system to form a polyalphaolefin product mixture. At least a portion of the polyalphaolefin product mixture is then isomerized in the presence of an acid catalyst to form an isomerized polyalphaolefin. The polyalphaolefin may also by hydrogenated, either simultaneously with isomerization or afterwards. The resulting polyalphaolefin has a kinematic viscosity at 100°C of between 1 cSt and 20 cSt and reduced pour point in comparison to the pre-isomerized product.
