| Title of Invention | “DEPOSIT DEACTIVATION TREATMENT METHOD” |
|---|---|
| Abstract | A method of treatment by which a deposit adherent to, e.g., the inside of a reactor in a process for producing an α-olefin oligomer is deactivated. After completion of the production of an ethylene oligomer in a reactor (10) in the presence of a chromium-based catalyst, a hydrocarbon solution containing an electron-donating compound such as water or an alcohol is supplied to the reactor (10) and a heat exchanger (16) to deactivate a deposit adherent thereto. |
