TL;DR: In this paper, a comprehensive overview on the fundamental understanding of water in brown coal and lignite, including the physical and chemical structure of coal, the forms of water present in low-rank coals, migration of water during drying, coal structure changes during moisture loss, moisture re-adsorption, and effects of water removal on subsequent applications including combustion, gasification and liquefaction are also summarized.

TL;DR: In this article, the Fourier transform infrared (FTIR) spectra of raw and dried lignite samples were curve-fitted to a series of bands in aliphatic hydrogen (3000-2800 cm-1) and carbonyl absorption (1850-1500 cm -1) zones.

TL;DR: In this paper, an integrated hot coal gas cleaning process is proposed with emphasis on simultaneous removal of multiple impurities including sulfur containing species, NO x precursors, mercury and tarry materials.

TL;DR: The kinetics analysis of NO absorption in EG-TBAB DESs indicated that EG- tetrabutylammonium bromide DESs could effectively absorb NO and the absorption of NO was strongly influenced by mass transfer, indicating that they are applicable in industrial denitrification processes.

TL;DR: In this paper, the desulfurization behavior of novel Fe and Fe-Mo sorbents supported using Chinese lignite chars for desulfuring hot coal gases was investigated and compared.
