Abstract

The high purity 1-octene produced by Sasol Alpha Olefins in Secunda and
which is sold to DOW Chemical Company for co-monomer application, has
performed poorly over the DOW Ziegler-Natta catalysts. The reason for the
poor performance was catalyst poisoning caused by low-level impurities
present in the 1-octene. Much work from Sasol and DOW has gone into
identifying the components responsible for catalyst deactivation, as well as
methods suitable for removing them without significant 1-octene losses.
Super NMP (n-Methyl-2-Pyrrolidone) extractive distillation piloting was
performed previously on 1-octene in order to remove the low-level impurities
that deactivate the DOW catalysts.
VLE (vapour liquid equilibrium) test work performed previously indicated that
all xylenol isomers are more promising as extractive distillation solvents than
NMP.
