Abstract: Unsaturated polyalpha-olefin (uPAO) materials comprising a mixture of vinylidene olefins, 1,2-di-substituted vinylene olefins, and tri-substituted vinylene olefins. The unsaturated PAO material can be made from alpha-olefin monomer(s) in the presence of a metallocene-compound-based catalyst system. The unsaturated PAO material can be used as intermediate material for making PAO materials having functional groups.

Abstract: The present disclosure provides processes and apparatus for producing poly alpha olefins. In at least one embodiment, a process to produce a poly alpha olefin includes introducing a first olefin monomer to a first catalyst and an activator in a first reactor to form a first reactor effluent comprising olefin dimers and olefin timers. The process includes heating the first reactor effluent to form an isomerized product and introducing the isomerized product to a filtration unit to form a filtration effluent. The process may include introducing the filtration effluent to a first distillation unit to form a first distillation effluent. The process may include introducing the first distillation effluent to a second distillation unit to form a second distillation effluent. The process includes introducing the first distillation effluent and/or the second distillation effluent to a second catalyst in a second reactor to form a second reactor effluent comprising the olefin timers.

Abstract: Methyl paraffins formed by hydrogenating one or more LAO dimers comprising a vinylidene moiety or a trisubstituted olefin moiety may have advantageous heat transfer properties, particularly when incorporated within an electric vehicle. For example, methyl paraffins produced upon hydrogenating LAO dimers formed from one or more C6-C12 LAOS, particularly in the presence of a Hf metallocene catalyst system, may contain 12-24 carbon atoms, and collectively have a flash point of about 130° C. or above, a pour point of about −42° C. or lower, a thermal conductivity at 80° C. of about 0.165 W/m·K or higher, and a Mouromtseff number ranging from about 17,000 to about 27,000 kg/(s2.2·m0.6·K) at 80° C. Heat transfer fluids comprising such methyl paraffins may be placed in contact with a heat-generating component, such as a battery and/or motor of an electric vehicle, or within a similar type of battery system, including immersive configurations for a battery.

Abstract: The present disclosure generally relates to processes to produce alpha-olefin oligomers and poly alpha-olefins. In an embodiment, a process to produce a poly alpha-olefin (PAO) includes introducing a first alpha-olefin and a first catalyst system comprising a metallocene compound into a continuous stirred tank reactor or a continuous tubular reactor under first reactor conditions to form a first reactor effluent. The alpha-olefin is introduced to the reactor at a flow rate of about 100 g/hr or more. The first reactor effluent includes PAO dimer comprising at least 96 mol % of vinylidene and 4 mol % or less of trisubstituted vinylene and disubstituted vinylene, based on total moles of vinylidene, trisubstituted vinylene, and disubstituted vinylene. The method includes introducing the first reactor effluent, a second alpha-olefin and a second catalyst composition comprising an acid catalyst into a second reactor under second reactor conditions to form a second reactor effluent comprising PAO trimer.
