Exploring the potential of petrographics in understanding coal pyrolysis
The effects of heating manner and charring temperature on both the physical and chemical properties of coal were investigated by petrographic techniques. Six coal samples of different rank were subjected to chemical treatment ...
Significance of coal properties on the caking degree of coarse coal particles mined at Limpopo Province, Republic of South Africa
(Taylor and Francis, 2020)
In this paper, a comprehensive coal property (chemical, mineralogical, physical, and petrographic) study was conducted using a caking coal from South Africa, density cuts and pyrolyzed samples to understand the % coal ...
The influence of calcium lignosulphonate addition on non-isothermal pyrolysis and gasification of demineralised bituminous coal fines
(Elsevier BV, 2022)
Amorphous calcium lignosulphonate (CaLS), a by-product of the paper industry, was evaluated as an adhesive to bind demineralised bituminous coal fines in various weight percentage ratios. Sequential acid (HCl, HF, ...
