Free hydrogen detected in the Songke-2 well (Songliao Basin, China) has a strong crustal
contribution. Here we evaluate whether the source could be the organic matter in Lower …

We have recently shown that molecular hydrogen generation from organic matter occurs at
high maturity levels (vitrinite reflectance 3–5%) in Lower Cretaceous shales of the Songliao …

Understanding pore heterogeneity is essential to obtain insights into the gas storage,
transport, and recovery from coal. The pore structure in analytical sample particles of …

To study the effect of isolated pores on gas seepage and coal deformation, computed
tomography (CT) scanning was used to analyse the porosity and fractal characteristics of …

The interaction between water/gas and rock plays an important role in evaluating initial fluid
storage in shale gas reservoirs. It is challenging to understand the co-occurrence …

The development of the pore network during the thermal cracking of organic matter in shale
plays an important role in the storage and transport of gas. There are several reports …

The formation and evolution of micropore was controlled by molecular structure to a certain
extent. To study the influence of chemical structure on micropore structure, a well …

It is essential to understand the law by which coal adsorbs water to prevent coal and rock
disasters in the mining process. However, the hydration of coal containing inorganic …

The synthesis of carbon onions in the laboratory by various methods is common; however,
naturally occurring carbon onions have only been found in a few geological samples on …

Coal is a carrier of carbon enrichment, so it has the potential for the preparation of coal-
based carbon materials. In this paper, LT anthracite and TSG bituminous coal were selected …
