Title
(EN) MANUFACTURE OF LOW VISCOSITY POLY ALPHA-OLEFINS
(FR) FABRICATION DE POLY-ALPHA-OLÉFINES) DE FAIBLE VISCOSITÉ
Abstract
(EN)
The present invention relates to poly alpha-olefins (PAO 's) which exhibit superior Noack volatility at low pour points. The poly alpha-olefin is prepared from an olefin feed comprised of a blend of octene, decene, and dodecene, the feed comprising at least 10 weight % octene and at least 30 weight% dodecene. The process includes both synthesis and distillation of the olefin and oligomerization olefin. The oligomerized olefin feed yields at least 50% low viscosity PAO having a nominal viscosity at 100° C of about 4 cSt.
(FR)
La présente invention porte sur des poly-alpha-oléfines (PAO) qui présentent une volatilité Noack supérieure à de faibles points d'écoulement. La poly-alpha-oléfine est fabriquée à partir d'une charge d'alimentation d'oléfines constituée d'un mélange d'octène, de décène et de dodécène, la charge d'alimentation comprenant au moins 10 % en poids d'octène et au moins 30 % en poids de dodécène. Le procédé comprend à la fois la synthèse et la distillation de l'oléfine et l'oligomérisation de l'oléfine. La charge d'alimentation d'oléfines oligomérisées produit au moins 50 % en poids de PAO de faible viscosité ayant une viscosité nominale à 100°C d'environ 4 cSt.
