Abstract
Official abstract text for this publication.
Provided is a method for disposal of a photocured waste by photooxidation-catalytic pyrolysis coupling. The method includes: subjecting a photocured waste to be disposed to photooxidation, and subjecting a resulting photocured waste after the photooxidation to catalytic pyrolysis; where the photooxidation is conducted by subjecting the photocured waste to be disposed to irradiation with ultraviolet light in air. In the method for disposal of the photocured waste by the photooxidation-catalytic pyrolysis coupling provided by the disclosure, the photocured waste to be disposed is subjected to the photooxidation, and the resulting photocured waste after the photooxidation is subjected to the catalytic pyrolysis.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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. 2 . The method of claim 1 , wherein the ultraviolet light has a wavelength of 254 nm to 405 nm. 3 . The method of claim 1 , wherein the irradiation is conducted at a power of 6 W to 85 W for 12 h to 288 h. 4 . The method of claim 1 , wherein the method further comprises grinding the photocured waste to be disposed into an 80-mesh powder before the photooxidation. 5 . The method of claim 1 , wherein the catalytic pyrolysis is conducted at a temperature of 400° C. to 700° C. for 10 min to 30 min.
