PURPOSE:To carry out the oligomerization of an aliphatic olefin in the presence of a catalyst having a specific Al/M atomic ratio and obtained by treating a composition supporting a transition metal (M) with a halogen-containing alkyl aluminum compound. CONSTITUTION:An oxide of a transition metal (M) selected from Ni, Co, Cr and Pd is supported on an acidic oxide (e.g. alumina, zeolite, etc.), and the obtained composition is treated with a halogen-containing alkyl aluminum compound (e.g. ethylaluminum sesquichloride) to obtain a catalyst having an Al/M atomic ratio of 0.5-10. A 2-6C aliphatic olefin is oligomerized in the presence of the above catalyst. Preferably, the olefin is a dehydrated aliphatic olefin containing extremely small amount of diolefin and is used together with hydrogen. |
