            Carrier series

            This series products consist of X-ρ active aluminum oxide,which is made by quick dehydration method,and pseudo boehmite aluminum oxide gel powder,which is made by wet method.These are prepared by advanced forming technology.They have the advantages of stable specific surface area,strong crushing strength,low abrasive rate,proper pore structure,low impurities and good impregnation of active component etc.The different catalyst carrier with different crystal phase,pore size and impurity content can be prepared by different process conditions according to the customers requirement.The are widely used in the petrochemical industry,HDS and PSA.
