Title:
HIGH-FREQUENCY INDUCTION PYROLYSIS APPARATUS FOR NITROUS OXIDE-CONTAINING GASEOUS COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/225980
Kind Code:
A1
Abstract:
The present invention relates to a high-frequency induction heating pyrolysis apparatus for decomposing nitrous oxide into nitrogen and oxygen, the apparatus enabling the treatment of nitrous oxide-containing gas mixture exhaust gas discharged in an adipic acid production process, a nitric acid production process, a caprolactam production process and a nitrous oxide production process. The high-frequency induction heating pyrolysis apparatus, according to the present invention, comprises: a high-frequency induction heating pyrolysis reaction system comprising a pyrolysis reactor which is formed from a metal material and has filled therein a filling material produced from metal, ceramic or aluminum nitride, and a high-frequency induction coil which is mounted around the pyrolysis reactor; a high frequency generator for generating a high frequency in the range of 3 to 30 MHz; a cooling system for cooling the high frequency generator and the high-frequency induction coil; and a temperature control system for controlling the internal temperature of the pyrolysis reactor. Nitrous oxide is decomposed into nitrogen and oxygen in the high-frequency induction heating pyrolysis apparatus according to the present invention.
