The organic hydrogen content of coal reduces with increasing coalification degree.
The organic nitrogen content of coal decreases with increasing coalification degree at greater depths.
Coalification has occurred naturally as a process mitigating high concentrations of atmospheric C[O.
The latter technique was developed early in the 20th Century with the aim of understanding the mechanisms of coal formation (Bergius and Specht 1913; Berl and Schmidt 1932), as the process of low-temperature HTC is considered to simulate natural coalification at accelerated rates (Hu et al.
