In addition, more attention should be given to the recycling of alkaline waste liquid and the application of coal-based solid waste zeolites in the field of volatile organic compound adsorption removal.īP p.l.c., Statistical Review of World Energy 2020, BP p.l.c., London. Finally, we propose an alkaline fusion-assisted supercritical hydrothermal crystallization as an efficient method for synthesizing coal-based solid waste zeolites. Furthermore, the application characteristics of various coal-based solid waste zeolites and their common application fields are illustrated. The synthesis processes of coal-based solid waste zeolite and their advantages and disadvantages are summarized. The mechanism and application characteristics of the pretreatment processes for zeolite synthesis from coal-based solid wastes are also introduced. In this paper, the physicochemical properties of coal gangue and coal fly ash are introduced. Zeolite derived from coal-based solid wastes (coal gangue and coal fly ash) can overcome the environmental problems caused by coal-based solid wastes and achieve valuable utilization.
