Description
Technical Field
[0001] The present application relates to the technical field of photothermal catalytic reactions, and in particular to a novel photothermal reactor. Background Art
[0002] Photochemical and photocatalytic oxidation are currently the most studied advanced oxidation technologies. The so-called photocatalytic reaction is a chemical reaction carried out under the action of light. Photochemical reactions require molecules to absorb electromagnetic radiation of a specific wavelength, which will be stimulated to produce an excited state of the molecules, and then chemical reactions will occur to generate new substances, or become intermediate chemical products that trigger thermal reactions. The activation energy of photochemical reactions comes from the energy of photons. Photoelectric conversion and photochemical conversion have always been very active research fields in the use of solar energy.
[0003] At present, the existing photothermal reactors are generally vertical, including a photothermal furnace, a reaction shell built into the photothermal furnace, and a quartz reaction tube built into the reaction shell for catalyst filling. Gas-phase materials and liquid-phase materials are introduced from the top of the reaction shell, and the reaction product gas is discharged from the bottom of the reaction shell. For liquid-phase materials, they are generally vaporized in a preheating furnace and then introduced into the reaction shell. The overall equipment requires two heating furnaces (photothermal furnace and preheating furnace), resulting in a large space occupied by the overall equipment, so further improvement is needed.
