1-Hexcene is an important comonomer for polyolefin and raw material for some other fine chemicals. Ethylene trimerization to 1-hexene is a process in which ethylene is converted to 1-hexene based on chromium catalyst. This technology possesses high selectivity and good product quality. A 50,000 t/a commercial plant of 1-hexene was built in 2007.  ‘50kt/a scale technology of ethylene trimerization to 1-hexene’ won the first prize of the science and technology progress of Sinopec in 2009，and National second prize of the technology invention award in 2015.
