Active alumina ball
Active alumina ball is the alumina that has porosity of absorption capability and catalytic activity,high disperse stength,large spcific surface area.It is available for dry of diversiform gas and liquid,and it can be used as absorbent,desiccant,catalyst and catalyst carrier in petroleum,chemical fertilizer ,chemical etc many reactive processes.
Active alumina is classified Ymodel and X~Pmodel by its inside main crystal compositive composition.According to its purpose,it can be classified active alumina absorbent,active alumina desiccant and active alumina catalyst carrier.
