Pyrolysis Pathway to Coal Clean Technologies IntechOpen
What is coal pyrolysis coal pyrolysis involves subjecting coal to high temperature of 400–450°C in the absence of oxygen When oxygen or steam is present coal will start burning and the process is no longer known as pyrolysis but rather referred as combustion and gasification

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
