Evolution of fuel-N in gas phase during biomass pyrolysis

Understanding and predicting fuel-nitrogen conversion during biomass pyrolysis is critical and continues to be a challenge for understanding formation and reduction of NOx and N2O during biomass combustion. This review examines the-state-of-the-art of nitrogen transformation mechanism during biomass pyrolysis. Proteins/amino acids, which are the nitrogen functionalities in biomass, decompose dependently of other constituents in biomass. The data obtained from pyrolysis of amino acid with the components in biomass are useful in predicting nitrogen conversion of biomass. Finally, directions for future research are suggested.
