概要

The reaction of phenol-formaldehyde resin char with NO was carried out at the temperature range from 850℃ to 1100℃. The nitrogen-containing species formed on char surface during the reaction were carefully examined by a high-speed gas chromatograph and a mass spectrometer. A large amount of N_2 and CO, small amount of N_2O and CO_2 were formed in the NO/Char reaction. In addition to these products, a significant amount of HCN was observed. The details of HCN formation mechanism was examined by step response method. It is founded that HCN was formed by way of C(N) as well as N_2 during NO/Char reaction, and HCN formation rate was affected by active hydrogen on char surface. The amount of C(N) produced by NO/Char reaction decreased at the high temperature range over 950℃ because of HCN and N_2 formation.
