Thermal Treatment under High-Vacuum of Tars Relevant in Combustion and Material Science

Chemical Engineering Transactions, 2017
The composition of tars, typically derived from coal and heavy fuel processing or formed in fuel-rich combustion, determines their transformation into carbons relevant in combustion and environmental fields as well as for material production.

Characteristics of Pyrolysis Products of Tar-Rich Coal Under Cryogenic Pretreatment with Liquid Nitrogen

Processes
The conventional pyrolysis of tar-rich coals faces limitations in maximizing tar yield and optimizing tar composition, often resulting in inefficient resource utilization and elevated emissions of CO2. This study investigates a novel cryogenic pretreatment method using liquid nitrogen to enhance pyrolysis efficiency, aiming to improve tar yield and ...

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.
