“…During pyrolysis, part of the fuel bound nitrogen (FBN) is released with the devolatilizing gases while the remainder is retained in the solid char to be released during subsequent gasification/combustion of the char [165,166]. The allocation of fuel-N to volatiles and char is dictated by temperature [160,[167][168][169][170], particle size [168], fuel type [160], residence time [168,170], heating rate [171], and pressure [171]. Temperature, fuel type, and particle size, are the dominant factors in this allocation while heating rate and pressure only have a minor effect.…”
