摘要：

The effects of thermal treatment in different solvents on the properties of magnetic spheroidal alumina catalyst carrier prepared by internal gelation process were investigated. After the precursors of alumina were treated in different solvents, the changes of crystal type, specific surface area, pore volume, magnetic property of the alumina were studied. With the increase of the treatment temperature and the treatment time, the specific surface area and pore volume increased respectively and the pore distribution altered largely. The physical and chemical properties of the magnetic alumina carrier satisfied the need of the catalytic hydrogenation of nitrobenzene an n-hexene.
