Abstract: 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.

Abstract: The system includes a dust collector, a pressure controller, a dryer, a gas heat-insulation device, a gas pool, a gas detector, an optical monitor and a computer sequentially connected. The dust collector is used to filter solid particles in a gas. The pressure controller is used to control a flow rate of the gas. The dryer is used to control a humidity of the gas. The gas heat-insulation device is used to control a temperature of the gas. The gas pool is used to carry the gas. The laser is used to irradiate the gas in the gas pool to generate a Raman scattering light. The gas detector is used to collect the Raman scattering light. The optical monitor is used to adjust and amplify a light signal of the Raman scattering light. The computer is used to output a Raman spectrum and a composition and content of a tar.

Abstract: A method for treating a waste plastic based on a persulfate system is provided. The method includes the following steps: mixing the waste plastic, sulfuric acid, sulfate, peroxymonosulfate, and water, and reacting at 80-140° C. for 3-15 h to complete the treatment; where the waste plastic is polyethylene or polyethylene terephthalate; and the sulfate is copper sulfate or ferrous sulfate. The present invention reasonably regulates and controls each parameter in the reaction process while constructing a homogeneous catalysis system of transition metal activated peroxymonosulfate, and finally directionally converts the waste plastic into C7H12 and C10H12 fuels, which realizes high-efficiency recycling of the waste plastic, has a simple and convenient working procedure, and has a wide application prospect.
