METHOD FOR THE PYROLYSIS OF POLYMERS
Disclosed is a method for the pyrolysis of a polymer comprising the steps of: introducing a reaction mixture resulting from pyrolytic reaction of a polymer in a pyrolysis reactor into an evaporator connected to the pyrolysis reactor at a high temperature, causing the reaction mixture to evaporate in...

| description | Disclosed is a method for the pyrolysis of a polymer comprising the steps of: introducing a reaction mixture resulting from pyrolytic reaction of a polymer in a pyrolysis reactor into an evaporator connected to the pyrolysis reactor at a high temperature, causing the reaction mixture to evaporate in the evaporator while blowing an inert gas into the evaporator, withdrawing volatile components separated from the reaction mixture from the evaporator, and withdrawing the reaction mixture from the evaporator. When the polymer is an olefin polymer, by this method, a pyrolytic wax of quality having satisfactory hue and a minimal content of contaminants is continuously produced in a stable manner for a long period. |
