METHOD FOR PYROLYTIC TREATMENT OF N2O, APPARATUS FOR PYROLYTIC TREATMENT OF N2O, AND METHOD FOR PLANNING APPARATUS FOR PYROLYTIC TREATMENT OF N2O

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently performing the pyrolytic treatment of N₂O at a high decomposition rate in a short time, an apparatus for realizing the efficient pyrolytic treatment of N₂O, and a method for planning the apparatus.;SOLUTION: The method for the pyrolytic treatment of N₂O includes a heating process for heating gas to be treated containing N₂O to a N₂O pyrolytic temperature region and a pyrolytic process for treating the gas to be treated at a predetermined pyrolytic temperature for a predetermined time after the heating process and, in the pyrolytic process, the Reynolds number of the gas to be treated is set to a turbulent flow region of 4,600-10,000 in the pyrolytic process to obtain an N₂O pyrolytic ratio of 90% or above within a pyrolytic temperature range of 950-1,000°C and a treatment time range of 0.7-2.0 sec.;COPYRIGHT: (C)2012,JPO&INPIT
