摘要:
铝是当今世界上除钢铁外使用量最大的金属,在各行各业均有广泛应用,在化工产业的废料中也含有各种铝盐,如果不加以利用,不仅会对环境带来污染,也是有限资源的浪费. 利用工业废水中的铝盐 (四氯铝酸钠)制备了活性氧化铝多孔材料. 固体四氯铝酸钠用过量的乙醇水溶液溶解后加入过量水生成六水合三氯化铝,然后制备得到不同浓度的水合氧化铝,调节pH值,控制老化时间形成α-水铝石,再用滴加法滴入油胺柱内形成球状物,干燥后放入马弗炉中焙烧得到活性氧化铝多孔材料. 制备得到的活性氧化铝比表面积在173 m2/g,孔容能达到1.34 m3/g,大孔分布(孔径大于100 nm)50%以上,介孔分布比较理想,适合作为吸附剂或者催化剂载体.
Abstract:
Alumina is widely used in many areas as the largest consumption followed steel and iron in the world. If the alumina-contained solid wastes from chemical industries are not utilized properly, they not only cause environmental pollution,but also waste the limited sources. In this paper, the preparation of active alumina oxide porous materials from sodium tetrachloroaluminate was studied. Solid sodium tetrachloroaluminate was dissolved with extra amount of alcohol and produced aluminium trichloride with different concentrations. Then we adjusted the pH values and controlled aging time to produce pseudo bohemite. Finally, the active alumina oxide was obtained by adding oleyl amine and drying. The prepared materials have a good pore distribution and can be used as adsorbent or catalyst carrier with high surface area of 173 m2/g, pore volume of 1.34 m3/g, and macropore(larger than 100 nm) friction above 50%.
