The behaviour of rare earth elements from South African coal fly ash during enrichment processes: wet, magnetic separation and zeolitisation
(MDPI, 2021)
are earth elements (REEs) are essential raw materials in a variety of industries including clean energy technologies such as electric vehicles and wind turbines. This places an ever-increasing demand on global rare earth ...
Acylation of anisole with benzoyl chloride over rapidly synthesized fly ash–based hbea zeolite
(Frontiers Media, 2021)
Stable HBEA zeolite with high surface area and strong acid sites was synthesized from coal
fly ash–based silica extract via indirect hydrothermal synthesis. The rapid HBEA
hydrothermal crystallization times of 8, 10, and ...
