Abstract
A study was also undertaken to examine whether the component (methylcyclopentadiene dimer as an example) that deactivates the catalyst is a temporary or permanent poison. Results showed that methylcyclopentadiene dimer is a temporary poison. The carbonaceous deposits (oligomers) formed during the reaction seem to be the primary cause of catalyst deactivation. However, the catalyst deactivation mechanism in the presence of water in 1-octene feed is mostly linked to the molecular structural change of the catalyst rather than accumulation of carbonaceous deposits on the surface of the catalyst.
