超增溶自组装制备纳米氧化铝渣油加氢催化剂载体

Preparation of alumina nanoparticles carrier for residue hydrogenation catalyst by supersolubilizing self-assembly technique

采用超增溶胶团自组装体原位合成纳米微粒方法合成了氧化铝渣油加氢催化剂载体,并通过扫描电镜、吸附脱附BET法和热重分析表征其结构。结果表明,制备的超增溶纳米自组装氧化铝载体性能稳定,分布均匀,具有较大的孔径、比表面积和孔容,强度高,堆积密度小,符合纳米粒子特性。

Alumina carrier for residue hydrogenation catalysts was prepared by supersolubilizing self-assembly mieelles and structure of the carrier was characterized by SEM, BET and TG. The results indicated that nanoparticles alumina carrier had good stability, even distribution, large pore size, surface area and pore volume, high strength and lower bulk density, which conformed to characteristics of nanoparticles.
