Homogeneous and heterogeneous formation of SO3 in flue gases burning high sulfur coal under oxy-fuel combustion conditions

Preparation of sulfur self-doped coal-based adsorbent and its adsorption performance for Cu2+

“…Currently, the application of high sulfur coal is limited. The combustion of high sulfur coal results in the release of signi cant amounts of sulfur dioxide, which contributes to air pollution (Xiao et al 2018). A large amount of solid waste is generated during ue gas desulphurization, including boiler ash and ue gas desulphurization gypsum (Tesárek et al 2007; Ye et al 2019), which have limited potential for combustion utilization (Tong et al 2023).…”

Density functional theory studies on ortho-position adsorption of SO3 at step sites of a CaO surface with SO2 and CO2

“…With the increasing demand of energy resources and the developing of coal mining technology, the deep coal seam is currently being mined, which mostly consists out of high-sulfur coal [1,2]. Unfortunately, combustion of this high-sulfur coal results in the exhaust of sulfur oxides which are known to cause severe environmental problems such as haze and acid rain [3][4][5]. Moreover, the sulfur oxides exhaust even further increases if oxy-fuel combustion is applied in order to carry out CO 2 capture and storage [6][7][8].…”
