The alumina carrier is a white solid, with two commonly used shapes, spherical and powdery. It is non-toxic, odorless, non-pulverized, and insoluble in water and ethanol. The calcination temperature is generally between 500-800℃. According to the pore volume, it can be made into mesoporous, macroporous and other carriers. The made carrier has the characteristics of strong activity, large pore volume and high water absorption. According to the purpose of the catalyst, appropriate active additives (such as: MO-Al, Ni-Al, Mn-Al, Ti-Al, CO-Al, K-Al, etc.) are added to the carrier to make catalysts for different purposes, which are used in petroleum Chemical, water treatment, environmental protection industries, fixed bed and moving bed environments can all be used differently. The spherical carrier can also be directly used as a catalyst by adding an appropriate amount of silicon oxide, iron oxide, copper oxide, titanium oxide, etc. to the carrier according to customer requirements. Commonly used packages are: 25 kg/bag, 25 kg/barrel, 100 kg/barrel
