外文摘要：Abstract Title: Catalyst composition for oligomerization of ethylene and processes of oligomerizationDisclosed are a catalyst composition for oligomerization of ethylene and processes of oligomerization, wherein the catalyst composition comprises chloride of Fe (II), Co (II) or Ni (II) complexed with 2-imino-1, 10-phenanthroline as the main catalyst and triethylaluminium as the cocatalyst. One of the processes of oligomerization of ethylene is using the above catalyst composition, and a molar ratio of metallic aluminum in the cocatalyst and the central metal in the main catalyst is from 30 to less than 200. The other process of oligomerization of ethylene is using the above catalyst composition, and the reaction temperature of oligomerization of ethylene is -10 ~ 19℃. The price of triethylaluminium as the cocatalyst is low, the use amount of the cocatalyst is small, and the cocatalyst has better catalytic activity, therefore the cost of oligomerization of ethylene reduces significantly, and the oligomerization of ethylene has wide industrial application prospect.
