Co-evolution with pore and molecular structure during tar-rich coal pyrolysis

Case Studies in Thermal Engineering
In-situ pyrolysis of tar-rich coal is a potentially green and low-carbon development technology. However, there are restrictions on the transport of tar and gas products due to the evolution of pore structure during pyrolysis. Hence, revealing the evolution of pore structure during pyrolysis is helpful to understand this restraining behavior.
