Differences in molecular structure and pyrolysis behavior of tar-rich coals influenced by accumulation conditions of coal-forming materials: a comparative study of coals from the Xishanyao Formation and Badaowan Formation in the Santanghu basin

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
The Santanghu Basin in Xinjiang, China, hosts significant tar-rich coal resources, yet marked disparities in tar yields exist between coals derived from the Badaowan and Xishanyao formations, complicating resource exploration and utilization.

An Effective Approach for Separating Carbazole and Its Derivates from Coal-Tar-Derived Anthracene Oil Using Ionic Liquids

, 2018
Carbazole and its derivates are important value-added chemicals (VACs) in anthracene oil (AO), which is one of the coal tar fractions. In this work, imidazolium-based ionic liquids (ILs) were used as novel extractants to extract carbazole from AO and the

Main factors that control roadway damage when a steeply dipping coal seam crosses a fault

Geomatics, Natural Hazards & Risk
When the working face of a steeply dipping coal seam crosses a fault, the dynamic disturbance caused by the mining load induces fault activation, causing large deformation and failure of the roadway.

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.

Environmentally sound coal-derived binder for coal briquetting

, 2002
Conventional coal binders such as coal tar pitch and petroleum refinery residue provide agglomerates of satisfactory quality. However, their use has been banned for a quarter century due to their hazardous effect on human health and their contribution to
