Sample preparation. Lignite(10 g) and KOH(5 g) were added to a 250 mL beaker, then adding 100 mL deionized water to mix them thoroughly in a water bath at 55 °C for 1 h. The mixture was cooled to room temperature, then centrifuging at 3400 r/min for 4 min. The upper clear layer was taken and centrifuged again by adding deionized water until.
Sample preparation. Lignite particles were dried in an oven at 105° C for 12 h and were crushed by a rod mill. Two kinds of size distribution particles were obtained by screening through 40 and 200 mesh sieves. Coarse and fine particles were mixed at a mass ratio of 6:4 in a disposable cup. The mass of dried lignite of a single sample is 40 g ...
Demineralized lignite preparation. The lignite from the No. 2 mine of Shengli coalfield in Xilinhot, Inner Mongolia, China was used as the raw material. After crushing and screening, Shengli lignite with a size of 200–400 mesh was selected and dried at 105 °C for 4 h as the raw coal (named SL). A mixture of SL and 18% hydrochloric acid (1 g ...

Coal resources, particularly lignite, are critical strategic energy sources accounting for approximately 45 % of global reserves [1].Coal fires caused by lignite are common owing to its low metamorphism, high chemical activity, and strong spontaneous combustion tendency, which leads to resource wastage, environmental pollution, and potential casualties [2].
Sample preparation and experimental procedure. The selected lignite samples were retrieved from a coal mine in Inner Mongolia. The dried samples to 40–80 mesh …
The preparation method of the FeS@LH refers to our previous study [15]. And the specific steps are as follows: The hydrogels were prepared by dissolving 15.00 g AM, 6.65 g MAH, 0.10 g NMBA, and 1.60 g LS-Na in 100 mL pure water. The mixture solution was stirred for 2 h at room temperature to achieve complete dissolution.
