N2 - • Coal B had a more aromatic structure due to the difference in distribution of sub-macerals, despite similar parent coal properties - More aromatic, lower reactivity, slower conversion • The coal with the higher inertinite content will retain energy in the aromatic ring structure, leading to a slower reaction. - This leads to remnant volatile matter and fixed carbon in the ash. • Allocation of reactive and inert sub-macerals appears to be very valuable - provided some indication to a possible reason for the difference in performance between these two coals.
