Abstract: | The formation of cyano group-containing polycyclic aromatic compounds (cyanoarenes) and nitrogen-containing aromatic compounds (azaarenes) during combustion processes is described. The experiments were carried out by combustion of nitrogen containing polymers (nylon 6, polyacrylonitrile and polyamide) in a combustion chamber ,to simulate combustion processes of waste incineration plants. The result from experiments, in which only one nitrogen containing polymer was burnt, showed the formation of several cyanoarenes. We conclude that during combustion processes in which hydrogen cyanide is formed, air pollution by cyanoarenes and azaarenes (in ppb or ppm concentrations) may occur. |
