    摘要: Unsaturated and hydrogenated polyalpha-olefin products can be made with a high selectivity toward vinylidenes and tri-substituted vinylenes combined, a high selectivity toward vinylidenes, and a low selectivity toward 1,2-di-substituted vinylenes by using a catalyst system comprising a metallocene compound having the following structure in the polymerization reaction: In formula (F-MC), Rl and R4 are each independently a hydrogen or a C1-C30 hydrocarbyl group, R2 and R3 are each independently a C1-C50 hydrocarbyl group, R5, R6, R7 and R8 are each independently a hydrogen or a C1-C30 hydrocarbyl group, provided that R6 and R7 are not both hydrogen. The first Cp ring and the second Cp ring may be annelated but not simultaneously.

    摘要: 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.
