Reaction Engineering of Direct Coal Liquefaction
Energies, 2009 Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country.

Advanced Materials Interfaces, EarlyView.The design, optimization and characterization of a new bilayer painting system is presented. The underlying layer is engineered to provide exceptional thermal insulation through the synergistic effect of hollow perlite microspheres and micrometer‐sized cellulose particles. The external painting layer is designed to induce the formation of a homogeneous

Techno-Economic Assessment of Co-Hydrothermal Carbonization of a Coal-Miscanthus Blend
Energies, 2019 Co-Hydrothermal Carbonization (Co-HTC) is a thermochemical process, where coal and biomass were treated simultaneously in subcritical water, resulting in bulk-homogenous hydrochar that is carbon-rich and a hydrophobic solid fuel with combustion ...

Известия Томского политехнического университета: Инжиниринг георесурсов, 2022 The relevance. Hard coals of the Mezhegey deposit are used mainly as a sintering additive for coke production. However, the heterogeneity and multicomponent nature of coal composition make it possible to consider coal as a raw material for deep chemical ...

Spontaneous combustion of coals and coal-shales
International Journal of Mining Science and Technology, 2018 Spontaneous combustion of coal is a well-known phenomena around the globe. Apart from the coal itself, burning coal-shales is becoming a problem in the South African coal mines. Serious incidents of spontaneous combustion have been reported as a result of self-heating of reactive coal-shales. The intrinsic properties and spontaneous combustion tests of
