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 Size: 3mmï¼?6mmï¼?8mmï¼?9mm, 10mmï¼?13mmï¼?16mmï¼?19mmï¼?25mmï¼?30mmï¼?32mm, 38mmï¼? 50mmï¼?65mmï¼?70mm 75mm Packing: 1) Normal package: in 25kg net woven polythene bags, on a pallet if necessary. 2) Steel pail: in 100L steel pails, on a pallet if necessary. Product Advantages: The alumina produced by China Aluminum Corp. is used as the base material, which provides high purity, little impurity and stable quality. Production is implemented on kanban basis and the entire production process is controllable and traceable. Each batch of product is strictly tested. The process and result guarantee stable performance and proven quality of the final product.
