Abstract

Investigations of fuel nitrogen release during pyrolysis/gasification of four coal samples in different gas atmospheres, including N₂, CO₂, 3%O₂/CO₂ and 6%O₂/CO₂, are performed in a U tube fixed-bed quartz reactor via temperature-programmed heating. The results show that the dominant N-containing species (excluding N₂) are HCN during temperature-programmed pyrolysis and NO is also detected besides HCN for coals with high oxygen content. No NH₃ is detected in all experiments, and N₂O is formed in an atmosphere with oxygen. The total fixed nitrogen (TFN) increases firstly and then decreases with increased O₂.
