ZEOLITES BASED ON WASTE INCINERATION FLY ASH AND PREPARATION METHODS THEREOF

原文（中国語）

A method for preparing zeolite based on waste incineration fly ash is provided, including: step (a) subjecting the waste incineration fly ash to acid washing to remove impurities, followed by water washing and drying; and step (b) adding a mixture of FeCland FeSOto washed and dried waste incineration fly ash, followed by mixing with a alkaline solution, putting into a ball milling tank together with grinding balls for a mechanical chemical reaction, and heating reaction materials in a process of ball milling to obtain the zeolite; a mass ratio of FeSOto FeClin the mixture being 5.5:1 and a mass ratio of the washed and dried waste incineration fly ash to the mixture being (5-10):1. The method employs acid washing to effectively remove most impurities from the waste incineration fly ash, significantly enhancing a ratio of silicon to aluminum, thus improving the purity of the synthesized zeolite.
