  • Name: High-purity Alumina Packing Ball
  • ID: WIN-QT92-01
  • Views : 4885

Applications: Widely used as underlying packing material for the hydrocracking systems, refining systems, CRCC systems, isomerizing systems and demethylating systems of petrochemical plants, chemical fiber plants, alkylbenzene plants, aromatic plants, ethylene plants and natural gas plants, and as the supporting or covering material for catalysts, molecule sieves and dryers inside reactors and packing material for towers. It primary purpose is to increase the gas or liquid distribution points, and support and protect less strong active catalysts.
Features: High purity, large strength; heat, high pressure and strong acid corrosion resistant; sound thermal vibration stability and stable chemical performance
