“…It is extremely important to prevent spontaneous combustion of coal in mines by studying the secondary oxidation of lignite at different pre-oxidation temperatures. The characteristic parameters of the spontaneous combustion of lignite were analyzed by simultaneous thermal analysis-Fourier transform infrared spectroscopy and in situ infrared spectroscopy experiments from the perspective of coal oxidizing, exothermicity and structural functional groups. …”

“…The article describes a process based on the hydrogen recovery of dust removal ash from lignite pyrolysis. The high volatile components in lignite will produce a large amount of H(2) during the pyrolysis process, which can replace part of C to reduce zinc and iron oxides in dust removal ash, thereby achieving the goal of reducing carbon consumption. …”
