Recent advances in the synthesis and application of zeolites from coal-based solid wastes
High-value utilization of coal-based solid wastes is in urgent demands for the sustainable development of natural resources,and one promising strategy is to prepare zeolites by using coal-based solid wastes as raw materials.In this review,the formation mechanism and primary properties including chemical composition,mineral property,structural and morphological characteristics of four typical coal-based solid wastes(gangue,fly ash,gasification slag,and liquefaction slag)were introduced in detail.The main methods of activation pretreatments and zeolite crystallization were further summarized systematically.Moreover,the application advantages of zeolites prepared from coal-based solid wastes in gas/liquid adsorption and heterogeneous catalysis were discussed by specific cases.It is expected that more prospective studies on low-energy activation,diverse framework,and application exploration are highly desired for the synthesis and utilization of zeolites from coal-based solid wastes.
