Study on molecular structural heterogeneity of tar-rich coal based on micro-FTIR

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy
The coal molecular structure in micro-areas plays a critical role in matrix thermal conduction and volatile generation during the pyrolysis of tar-rich coal. However, as a major maceral contributing to hydrocarbon generation, the molecular structures of different micro-areas in vitrinite show heterogeneity, which still lacks research.

Experimental investigation on thermal conductivity of tar-rich coal under the simulated in-situ conditions

Fuel
The thermal conductivity of tar-rich coal is an important parameter for optimizing the underground heating method. In this study, the thermal conductivity of tar-rich coal was measured in an experimental system in which the in-situ conditions can be simulated. The pore-fracture structure of tar-rich coal samples under different pyrolysis conditions was
