Method for disposal of photocured waste by photooxidation-catalytic pyrolysis coupling

A method for improving a quality of pyrolysis oil prepared by catalytic pyrolysis of a photocured waste, the method comprising:

• subjecting a photocured waste to be disposed to photooxidation;
• and
• subjecting a resulting photocured waste after the photooxidation to catalytic pyrolysis,
• wherein the photooxidation is conducted by subjecting the photocured waste to be disposed to irradiation with ultraviolet light in air,
• wherein the catalytic pyrolysis is conducted by using a molecular sieve catalyst, and
• wherein during the catalytic pyrolysis, the resulting photocured waste after the photooxidation and the molecular sieve catalyst are mixed in a mass ratio of 1:1 to obtain a mixed sample, and then the molecular sieve catalyst with a same mass is taken to cover a surface of the mixed sample for the catalytic pyrolysis.
