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, a Chinese lignite coal was dried in a fluidized-bed reactor in the presence of air and nitrogen to examine the effect of temperature, particle size, gas flow rate, and sample mass.

TL;DR: In this article, the drying kinetics of Chinese lignite in nitrogen fluidized-bed, superheated steam fluidizedbed and microwave were investigated and the changes in the mass as a function of drying time were measured under various drying conditions.

TL;DR: In this paper, the characteristics of chars from low-temperature pyrolysis of two lignite coals have been investigated using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR).
