  • Zeolite derived from coal-based solid wastes (coal gangue and coal fly ash) not only can cope with the environmental problems caused by coal-based solid wastes but also achieve their valuable utilization. In this paper, the physicochemical properties of coal gangue and coal fly ash were introduced. Then the mechanism and application characteristics of the pretreatment processes for zeolite synthesis from coal-based solid wastes were introduced as well. After that, the synthesis processes of coal-based solid waste zeolite and their merits and demerits were summarized in detail. Furthermore, the application characteristics of various coal-based solid waste zeolites and their common application fields were also illustrated. By the end of this review, we propose that alkaline fusion-assisted supercritical hydrothermal crystallization may be an efficient method for synthesizing coal-based solid waste zeolites. Besides, more attention should be paid to the recycling of alkaline waste liquid and the application of coal-based solid waste zeolites in the field of volatile organic compounds adsorption removal.
