英文摘要[中文文摘]将结晶氯化铝与柠檬酸及淀粉等造孔剂混合,经直接干燥和焙烧制得了一种无定形活性氧化铝,并通过X射线粉末衍射、N2物理吸附及氨程序升温脱附等手段对活性氧化铝样品进行了表征,探讨了各组分对活性氧化铝样品性质所起的作用.与常规的活性氧化铝制备方法相比,这种制法省去了中和、老化、过滤和洗涤等步骤,缩短制备周期且过程容易控制.活性氧化铝具有适宜且可调节的比表面积和孔径分布,作为载体负载镍金属组分制成负载型催化剂后,对乙苯加氢饱和与加氢裂化表现出较高的催化活性.[英文文摘]A novel and simple method was developed to prepare alumina with suitable specific surface area and pore size distribution. First,AlCl3·6H2O and citric acid were heated without water in a water bath at 90 ℃ with stirring until a homogenous solution was obtained.Then starch was added into is solution.After the solution was dried at 110 ℃ and calcined at indicated temperature, activated alumina was obtained.The activated alumina was characterized by N2 adsorption,X-ray diffraction,and NH3 temperature-programmed desorption. Compared with the usual technology , this novel preparation did not include some steps such as aging , filtering , and washing. Moreover , the specific surface area and pore size distribution of the activated alumina could be controlled and modified by changing the preparation parameters. The supported Ni/ Al2O3 catalyst with the activated alumina as support showed higher activity for hydrogenation and hydrocracking of ethylbenzene.; 国家重点基础研究发展计划(973计,2004CB217805); 福建省“百千万人才工程”项目; 福建省自然科学基金(U0750016)。
