“…A good removal capacity, which could be related to their textural properties, was shown by some samples. Sarmah et al [111] investigated the CO 2 capturing capacity of amine fly-ash-based composites. A comparison of material cost and adsorption capacity showed that they were cheap and efficient for CO 2 capture.…”

Coal fly ash, an industrial by-product, is derived from coal combustion in thermal power plants. It is one of the most complex anthropogenic materials, and its improper disposal has become an environmental concern and resulted in a waste of recoverable resources. There is a pressing and ongoing need to develop new recycling methods for coal fly ash. The present review first describes the generation, physicochemical properties and hazards of coal fly ash at the global level, and then focuses on its current and potential applications, including use in the soil amelioration, construction industry, ceramic industry, catalysis, depth separation, zeolite synthesis, etc.Finally, the advantages and disadvantages of these applications, the mode of fly ash utilization worldwide and directions for future research are considered.

“…Soe et al (2016) and Muvumbu (2015) emphasized that Ca ion-exchanged zeolites have excellent CO 2 adsorbability. Sarmah et al (2013) performed CO 2 adsorption experiments on CFA-based zeolite modified by monoethanolamine/N,N-dimethylaniline and diethylamine/N,N-dimethylaniline, and the adsorption capacity reached 6.89 and 5.99 mmol g -1 respectively. In addition, the modified zeolite had a lower cost and higher adsorption efficiency than commercial zeolite.…”

SO x , NO x , CO x , volatile organic compounds (VOCs), and Hg vapor directly and indirectly harm the atmospheric environment and human health by contributing to the formation of photochemical smog, acid rain, and haze and posing risks of potential toxicity (e.g., carcinogenicity). Therefore, effectively controlling and reducing the pollution caused by these chemicals is critical, and to that end, several methods have been developed, among which adsorption is one of the most common and effective techniques. As adsorption materials, zeolites show great potential in reducing air pollution. Moreover, coal fly ash (CFA)-based zeolite synthesis enables the simultaneous treatment of air and solid waste pollution. In this study, the progress of recent years in research on zeolite synthesis by CFA is reviewed, and the challenges besetting this method are discussed. In addition, we examine the application of CFA-based zeolites in removing or minimizing harmful gases. As we enter an era of utilizing disposed waste, developing efficient and low-cost materials for the removal of harmful gases may require improving the synthesis of high-purity, high-performance fly ash zeolite materials.

“…25 Sarmah et al prepared the mixed primary/tertiary amines (MEA/DMA) and mixed secondary/tertiary amines (MEA/DMA)-impregnated y ash-based sorbents, and the equilibrium adsorption capacity was up to 6.89 and 5.99 mmol g À1 in pure CO 2 , respectively. 26 The world's coal reserves are very rich, ranking rst among all energy sources, and pores and cracks formed in the process of preparing semicoke. Many researchers have studied the CO 2 adsorption performance of the coal and semicoke.…”
