Coal gasification fine slag (FS)-based activated carbons (ACs) for CO 2 capture provided a new method to realize the value-added utilization of FS. Furthermore, pre-oxidation treatment of carbonaceous materials is one of the most efficient possibilities to obtain developed pore structure of activated carbons to enhance the CO 2 adsorption capacity. In this study, four types of oxidizing agents ...

2021-3-23 To simulate the mechanical properties of coal, a coal block was collected from the #15 coal seam of the Tianchi coal mine and ground to coal powder. The coal powder was then mixed with Weihe River sand, cement, and gypsum to produce coal-like materials and reduce the gap between the specimens and the raw rock and coal in the field.
