DOI: 10.1016/j.fuel.2017.12.049

Abstract: Abstract The chemical structures of six coal samples with different ranks were semi-quantitatively characterized by a series of original infrared structural parameters, and the pyrolysis reactivity of the samples were quantitatively characterized by a comprehensive… read more here.

Published in 2021 at "Fuel"

DOI: 10.1016/j.fuel.2020.120087

Abstract: Abstract To investigate the effect of coal metamorphism on the probability of coal spontaneous combustion (CSC), five types of coal sample were subjected to a temperature-programmed testing system. The gas indicators and limiting parameters of… read more here.

Published in 2022 at "ACS Omega"

DOI: 10.1021/acsomega.2c02830

Abstract: Microorganisms are the core drivers of coal biogeochemistry and are closely related to the formation of coalbed methane. However, it remains poorly understood about the network relationship and stability of microbial communities in coals with… read more here.
