摘要
粉煤灰是煤燃烧后的固体废弃物,其高附加值利用是国内外关注的一个方向.目前粉煤灰合成分子筛研究热点主要集中在改进实验合成方法和降低合成成本.此文综述了由粉煤灰合成分子筛的国内外进展,阐述并比较了目前由粉煤灰合成方法的优缺点并指明了未来的研究方向.同时探讨了粉煤灰分子筛在土壤治理、废水处理、空气净化等方面的应用前景.因此利用粉煤灰合成具有高附加值分子筛产品是粉煤灰综合利用的一个发展趋势.
Coal fly ash is solid waste of coal post-combustion. To produce high value-added products from coal fly ash is an important research direction. Currently,the research on the synthesis of zeolites from fly ash focuses on the improvement of synthesis methods and reduction of cost. This paper reviewed the development of zeolties synthesis from fly ash with various methods and compared the advantages and disadvantages of those synthetic methods. Besides,the applications of fly ash zeolite in soil treatment,wastewater treatment and air purification are discussed. Thus,the utilization of fly ash in the synthesis of high value-added zeolite products is a trend of fly ash utilization.
