Abstract: Provided is a method for preparing an aromatic hydrocarbon-rich pyrolytic oil by catalytic pyrolysis of a waste mask, which relates to the technical field of waste treatment and resource utilization. The method includes: mixing the waste mask with a metal supported HZSM-5 molecular sieve catalyst to form a mixture; and subjecting the mixture to a catalytic pyrolysis reaction in a protective atmosphere to obtain the aromatic hydrocarbon-rich pyrolytic oil.
