摘要
粉煤灰是燃煤电厂产生的固体废弃物,其主要成分中包含大比例的SiO2、Al 2O3,是合成沸石的理想原料。粉煤灰合成沸石的方法随着研究的深入而逐渐成熟,从起初的一步水热法到现在的复合水热法,从以未经处理的粉煤灰为原料到现在使用预处理过的粉煤灰为原料,粉煤灰合成沸石的工艺一直在进步。从粉煤灰的预处理、合成沸石方法、产物应用领域三方面综述了研究进展,并对其整体发展趋势进行了展望。
Coal fly ash is a solid waste produced by coal-fired power plants.Its main components contain a large proportion of SiO2 and Al 2O3,and it is an ideal raw material for the synthesis of zeolite.With the deepening of research,the synthesis method of zeolite by coal fly ash has been gradually mature.From the initial one-step hydrothermal method to the present composite hydrothermal method,from raw coal fly ash as raw material to the pre-treated coal fly ash as raw material,the synthesis process of zeolite by coal fly ash has been progressing.The research progress in pretreatment of coal fly ash,synthesis method of zeolite and application field of the product are reviewed.And the overall development of zeolite based on coal fly ash is expected.
