One of the most important catalysts in oil, gas and petrochemical industries is gamma alumina. Different forms of alumina have also wide range of applications.
It is also the base of a great of required Industrial catalysts.
The spherical type of gamma alumina is very important because of its Special preparation process.
In this research the oil-drop method is applied for preparation of very Spherical activated alumina. Basic aginge stage was modified and the basic aging time& temperature decreased .The product was obtained with %98 efficiency.
