The influences of various physical parameters including the Casson fluid parameter, magnetic field strength, heat source/sink coefficient, and chemical reaction rate on velocity, microrotation, temperature, and concentration profiles are thoroughly investigated. The study reveals that magnetic damping, viscous resistance, and stretching elevate Casson nanofluid motion and thermal transport, with Brownian motion intensifying internal energy and thermal boundary thickness. Increasing chemical consumption actively removes flow species.

This study investigates the effect of acid-washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=O, C–O, and OH) in coals of varying ranks (lignite XDL, gas coal DJG, and coking coal QJC) using thermogravimetry (TG), X-ray diffraction (XRD), and in situ transmission Fourier transform infrared spectroscopy (in situ FTIR). Sequential hydrochloric acid-hydrofluoric acid (HCl-HF) treatment removes most inorganic minerals in coal while inducing structural reorganization, particularly in the higher-rank coal. For low-rank XDL, the functional group evolution remains largely unaffected, whereas medium- and high-rank DJG and QJC exhibit accelerated decomposition of aliphatic C–H, aromatic C=C, and C=O groups probably due to acid-induced pore formation or macromolecular destabilization. Minerals in the raw coals stabilized aromatic frameworks and catalyzed the conversion of C–O to C=O. Consequently, their removal suppressed hydrogen transfer and the cleavage of substituents on aromatic rings. Notably, demineralization by sequential acid washing delays C–O decomposition across all ranks but enhances OH retention in lignite while promoting dehydroxylation in higher-rank coals. These findings underscore a rank-dependent mechanism: structural reorganization dominates in high-rank coals, whereas mineral catalytic effects prevail in lower-rank matrices.

The results show that the main pathway for the generation of H<sub>2</sub>S in this area is the biological action of sulfate-reducing bacteria (SRB), rather than the traditional understanding of sulfur-containing organic matter thermal cracking or sulfate thermochemical reduction processes.

To effectively inhibit the generation of H<sub>2</sub>S, this study conducted a series of screening and optimization experiments on bactericides. The experimental results show that the two bactericides SW-60 and SW-80 have good bactericidal effects when added at a concentration of 100 mg/L.
