  • Formation of NOx precursors during the pyrolysis of coal

    Effects of pressure on the formation of HCN and NH 3 during the pyrolysis and gasification of Loy Yang brown coal in steam were investigated using a pressurised drop tube/fixed bed reactor The NH 3 yield increased with increasing pressure during both pyrolysis and gasification Increasing pressure selectively favours the formation of NH 3 at the expenses of other N containing species
