Abstract The present work reports the feasibility of valorizing waste glass and aluminum scraps into zeotype materials. The raw materials were reacted hydrothermally at 60 °C using alkaline fusion prior to hydrothermal treatment. The obtained powders were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), electron microscopy (SEM) and magic angle spinning nuclear magnetic resonance (MAS NMR) of 27Al and 29Si nuclei. The influence of some parameters like alkalinity, reaction time and particle size on the nature of obtained zeolites has been also studied. The characterization methods demonstrated that the final products are aluminosilicate materials with a high cation exchange capacity containing Na-FAU and Na–P1 zeolites. The above results show that valorization of waste glass and aluminum scraps to obtain Na-FAU and NaP1 zeolites is possible and can be a sustainable alternative to the traditional synthesis methods.

利用荧光灯管和铝屑的废玻璃合成高附加值的 Na-P1 和 Na-FAU 沸石

摘要 目前的工作报告了将废玻璃和铝屑转化为沸石材料的可行性。在水热处理之前,使用碱熔法使原料在 60 °C 下进行水热反应。所得粉末通过 27Al 和 29Si 的 X 射线衍射 (XRD)、X 射线荧光 (XRF)、傅里叶变换红外光谱 (FTIR)、电子显微镜 (SEM) 和魔角自旋核磁共振 (MAS NMR) 进行表征核。还研究了碱度、反应时间和粒径等参数对所得沸石性质的影响。表征方法表明,最终产品是含有 Na-FAU 和 Na-P1 沸石的具有高阳离子交换容量的铝硅酸盐材料。
