简介
The large emission of coal fly ash (CFA) brings a series of environmental and health problems. Therefore, it is extremely necessary and significant to explore efficient ways to reuse fly ash. Zeolitization of CFA provides a potential alternative for creating high-added-value products from this hazardous solid waste. But the synthesis of zeolite from CFA is still a long way from industrialization. In this paper, a single-phase submicron zeolite Y (FAZ-Y3) was successfully synthesized from CFA via the alkali fusion hydrothermal method without the use of any organic structure guide agents. Results indicated that the type and purity of zeolite greatly depended on the preparation parameters and zeolite P was the major competitive phase. With an average size of approximately 250 nm, FAZ-Y3 possessing a specific surface area of 386.9 m2 g−1 and crystallinity of 92.73% was prepared at 80 °C for 12 h by adding the inorganic …
