The present disclosure generally relates to process to produce a poly alpha-olefin (PAO), comprising: a) introducing a first alpha-olefin to a first catalyst system comprising non-aromatic hydrocarbon soluble activator and a metallocene compound into a continuous stirred tank reactor or a continuous tubular reactor under first reactor conditions, wherein the first alpha-olefin is preferbaly introduced to the reactor at a flow rate of about 100 g/hr or more, to form a first reactor effluent comprising PAO ( such as at least 60 wt% of PAO dimer and 40 wt% or less of higher oligomers, where the higher oligomers are oligomers that have a degree of polymerization of 3 or more); and b) introducing the first reactor effluent and a second alpha-olefin to a second catalyst composition comprising an acid catalyst, such as BF3, in a second reactor to form a second reactor effluent comprising PAO trimer.
本公开涉及一种生产聚α烯烃(PAO)的工艺,包括:a) 将第一α-烯烃引入包含非
芳香烃可溶活化剂和茂
金属化合物的第一催化剂体系中,进入连续搅拌罐反应器或连续管式反应器,在第一反应器条件下,其中第一α-烯烃首选以约100克/小时或更高的流速引入反应器,形成包含PAO的第一反应器流出物(例如至少60重量%的PAO二聚体和40重量%或更少的更高寡聚体,其中更高的寡聚体是具有3或更多聚合度的寡聚体);和b) 将第一反应器流出物和第二α-烯烃引入包含酸性催化剂(例如
BF3)的第二催化剂组合中,在第二反应器中形成包含PAO三聚体的第二反应器流出物。
