Identification of tar-rich coal based on the true density and natural gamma ray response of coals

Objective Tar yield, derived from the Gray-King assay, serves as the sole metric for evaluating tar-rich coal. However, insufficient exploration data hinder its effective application in the fine-scale evaluation of extensive tar-rich coal.

Production capacity prediction of U-shaped horizontal wells for in-situ pyrolysis of tar-rich coal: Experimental and numerical simulation study

Meitan xuebao
Under the goal of “dual carbon”, “taking hydrogen and retaining carbon” has become an inevitable choice for the clean utilization of coal, and underground coal pyrolysis provides a new idea for increasing domestic tar and gas production.

Preparation of Nitrogen-Rich Tar by Co-Pyrolysis and Analysis of Nitrogen-Containing Compounds in Pyrolysis Products

Applied Sciences
In this study, we use coal as a carbon source from Zhangjiamao and doped with different nitrogen sources for co-pyrolysis. Nitrogen-rich tar was successfully prepared, and the content and variety were also increased.
