TLDR
Coal chemistry: The action of solvents on coal and the action of oxidizing agents on coal Action of air and molecular oxygen on coal as mentioned in this paper, and the "grand processes" of coal utilization.Abstract:
Part 1 Coal Typology: Coal as an economic good Coal as fuel and raw material Coal as an organic sediment Coal as a rock Coal as a biological debris Coal as an evolving organic chemical complex Coal as a solid colloid Coal as an enigma in solid state physics Coal as an object of classical chemical analysis Coal as an object of physical analysis. Part 2 Coal Physics: Physical properties and the additivity concept Volumetric properties Optical properties Electrical properties Magnetic properties Mechanical properties Cohesive and interfacial energy properties Thermal properties. Part 3 Coal Chemistry: The action of solvents on coal The action of oxidizing agents on coal Action of air and molecular oxygen on coal The action of hydrogen on coal The action of heat on coals The "grand processes" of coal utilization. Part 4 Coal Constitution: The chemical and physical nature of coals Coal analogues Coalification revisited Coal research. Part 5 Compendium.read more

Hydrothermal carbonization of biomass residuals: a comparative review of the chemistry, processes and applications of wet and dry pyrolysis
Judy A. Libra,Kyoung S. Ro,Claudia Kammann,Axel Funke,Nicole D. Berge,York Neubauer,Maria-Magdalena Titirici,Christoph Fühner,Oliver Bens,Jürgen Kern,Karl-Heinz Emmerich +10 more
TL;DR: The wet pyrolysis process, also known as hydrothermal carbonization, opens up the field of potential feedstocks for char production to a range of nontraditional renewable and plentiful wet agricultural residues and municipal wastes as discussed by the authors.

Poisson's ratio values for rocks
TL;DR: In this paper, the effects of Poisson's ratio in the elastic deformation of materials, intact rocks, and rock masses are briefly reviewed, and the reported values of POI for some elements, materials, and minerals are compiled while typical ranges of values are presented for some rocks and granular soils.

CBM and CO2-ECBM related sorption processes in coal: A review
Andreas Busch,Yves Gensterblum +1 more
TL;DR: In this article, the state of the art on water and CO2 sorption on coal seams is reviewed and compared using manometric, volumetric and gravimetric methods.
Journal ArticleDOI
Kinetics in solids
TL;DR: How an alternative "model-free" approach to kinetic analysis, which is based on the isoconversional method, can overcome some of these limitations of the widely practiced force fitting of experimental data to simple reaction-order kinetic models is discussed.

FTIR and Raman spectroscopy characterization of functional groups in various rank coals
TL;DR: In this paper, the chemical and physical properties of coal were investigated using FTIR and Raman spectroscopy, and correlations were established for these parameters, showing that coal structure is complex with three stage characteristics at R o ǫ = 0.4 −1.4−1.3, 1.3 −2.0% and 2.0 −4.0%.
