Early maturation processes in coal. Part 1: Pyrolysis mass balances and structural evolution of coalified wood from the Morwell Brown Coal seam [PDF]

, 2009
In this work, we develop a theoretical approach to evaluate maturation process of kerogen-like material, involving molecular dynamic reactive modeling with a reactive force field to simulate the thermal stress. The Morwell coal has been selected to study

Occurrence of tar-rich coal: review and perspectives

Australian Journal of Earth Sciences
Tar-rich coal, a unique coal type characterised by dual attributes as both a resource and energy carrier, holds significant implications for the development of coal-based hydrocarbon resources and the implementation of carbon neutrality strategies. This study systematically reviews the geological–biochemical processes governing the formation of tar ...
