The alumina carrier is a white solid with two common shapes, spherical and powdery, non-toxic, odorless, non-powdery, insoluble in water and ethanol. The calcination temperature is about 500-800 ℃. According to the size of pore volume, mesoporous and macroporous carriers can be made. The carrier made has strong activity, large pore volume and high water absorption. According to the purpose of the catalyst, add appropriate active additives (such as MO-Al, Ni-Al, Mn-Al, Ti-Al, CO-Al, K-Al, etc.) into the carrier to make catalysts for different purposes, which can be used in petrochemical, water treatment, environmental protection industries, fixed bed and mobile bed environments. 

Spherical support can also be directly used as catalyst by adding appropriate amount of silicon oxide, iron oxide, copper oxide, titanium oxide, etc. into the support according to customer requirements. 

Common packaging: 25kg/bag, 25kg/barrel, 100kg/barrel.
