摘　　要：粉煤灰是世界排放量最大的工业废渣之一,对环境的污染越来越严重。结合粉煤灰的化学成分及性质,综述了粉煤灰合成沸石分子筛的传统方法及新方法,对不同的合成方法的优缺点进行了评价,展望了粉煤灰制备沸石分子筛的发展方向,为粉煤灰的资源化利用开辟了新途径。Fly ash was one of the industrial solid wastes with the largest discharge in the world and caused more and more serious environmental pollution.According to the properties and the chemical composition of the fly ash,the traditional synthesis method and new method that made use of fly ash to prepare zeolite were overviewed,and the advantage and the disadvantage of different synthesis methods were evaluated.The development direction that the fly ash made for the zeolite molecular sieve was expected and the resource utilization of the fly ash were opened up in a new way.
