Decoupling Mineral Shielding and Carbon-Structure Inertness in Pressurized Coal Gasification Fine Slag Combustion via Sequential Demineralization

Abstract Pressurized coal gasification fine slag exhibits poor combustion reactivity due to the coupled effects of mineral encapsulation and highly ordered residual carbon. In this study, sequential HCl → HF → HNO3 demineralization was employed as a mechanistic probe to distingui...
