Comparative study on pollution characteristics of heavy metals and polycyclic aromatic hydrocarbons in coking solid wastes Open
Coking, an important method of coal utilization, inevitably produces various solid wastes, including coke powder (CP), tar residue (TR), oil‐washing sludge (OS), and coking sludge (CS). Although previous studies have focused on the polluta…

An efficient and template‐free synthesis of mesoporous silica from coal fly ash Open
In the study, the desilication liquids and acid‐leached residues derived from the “alumina extraction process” of coal fly ash (CFA) were used as raw materials to prepare sodium silicate precursor. Then, the mesoporous silica with controll…
