Title
(EN) PROCESSES FOR PRODUCING POLY ALPHA OLEFINS AND APPARATUSES THEREFOR
(FR) PROCÉDÉS DE PRODUCTION DE POLY ALPHA-OLÉFINES ET APPAREILS ASSOCIÉS
Abstract
(EN)
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.

La présente invention concerne des procédés et des appareils pour la production de poly alpha-oléfines. Dans au moins un mode de réalisation, un procédé de production d'une poly alpha-oléfine comprend l'introduction d'un premier monomère d'oléfine sur un premier catalyseur et d'un activateur dans un premier réacteur pour former un premier effluent de réacteur comprenant des dimères d'oléfines et des trimères d'oléfines. Le procédé comprend le chauffage du premier effluent de réacteur pour former un produit isomérisé et l'introduction du produit isomérisé dans une unité de filtration pour former un effluent de filtration. Le procédé peut comprendre l'introduction de l'effluent de filtration dans une première unité de distillation pour former un premier effluent de distillation. Le procédé peut comprendre l'introduction du premier effluent de distillation dans une seconde unité de distillation pour former un second effluent de distillation. Le procédé comprend l'introduction du premier effluent de distillation et/ou du second effluent de distillation sur un second catalyseur dans un second réacteur pour former un second effluent de réacteur comprenant des trimères d'oléfines.
