Comparative study of low temperature denitration performance of Mn-Ce/ACFA-TiO2 catalysts under oxy-fuel and air-fuel combustion flue gases

Gou, Xiang; Zhang, Ruiping; Xu, Guoyou; Zhao, Dong - In: Energy Reports 6 (2020), pp. 1545-1552

Low temperature selective catalytic reduction (SCR) catalysts were prepared by using acetic acid modified fly ash (ACFA) and TiO2 with the loading of Mn-Ce. The powder catalysts were characterized by BET, XRD and SEM. The effects of Mn-Ce molar ratio on the NO conversion of SCR catalyst were...

Pre-processing of coal combustion fly ash by classification for enrichment of rare earth elements

Lanzerstorfer, Christof - In: Energy Reports 4 (2018), pp. 660-663

Fly ash from the combustion of coal shows potential as a source of valuable metals like the rare earth elements (REEs). These are present in the fly ash at low concentrations. Thus, simple dry pre-processing methods that can produce REE-enriched fractions from the fly ash could improve the...
