Influence of ionic liquid pretreatment on coal desulfurization

Gongcheng Sun et al.

Summary: Combining ionic liquid pretreatment with H2O2 oxidation desulfurization proves to be an effective method for enhancing the removal of sulfur from coal. Ionic liquid pretreatment can promote coal desulfurization, increasing the specific surface area and pore size of coal samples, thus improving sulfur removal efficiency.
