Abstract

The fly ashes (Class F and C) have been successfully used as the main substrates in the hydrothermal syntheses of Na-A, Na-P1, Na-X and sodalite zeolites. Both ashes and their derivatives after milling with magnetic field grinder were used. The paper investigates the effect of fly ash fraction size on the syntheses efficiency and physicochemical properties of the obtained zeolites. The starting material and obtained zeolites were subjected to physicochemical characteristics using X-ray diffraction, X-ray fluorescence, particle size analysis, and scanning electron microscopy methods. The paper showed a significant effect of the used fly ash fractions on the quantity, purity, quality and level of crystallinity of the zeolites phase obtained. The application of the grinding process prior to the syntheses of zeolites, with a relatively small financial outlay, significantly increases their application potential. Obtained zeolites are a promising material in the context of their use, inter alia, in environmental protection.

磨削后粉煤灰分率对Na-A，Na-P1，Na-X和方钠石型沸石水热合成效率的影响

摘要

粉煤灰（F级和C级）已成功用作Na-A，Na-P1，Na-X和方钠石沸石水热合成的主要基质。使用磁场研磨机研磨后的灰烬及其衍生物均被使用。本文研究了粉煤灰级分的大小对所得沸石的合成效率和理化性质的影响。使用X射线衍射，X射线荧光，粒度分析和扫描电子显微镜法对原料和获得的沸石进行理化特性分析。该论文显示了所用的粉煤灰馏分对所获得的沸石相的数量，纯度，质量和结晶度有显着影响。在合成沸石之前先进行研磨工艺，相对较小的财务支出，显着增加了其应用潜力。就其在环境保护中的用途而言，获得的沸石是有前途的材料。
