Inert Alumina Ceramic Balls as Catalyst Bed Supports.
ceramic balls and alumina balls for adsorbent and catalyst bed supports.
Inert alumina ceramic ball is one of the new media in chemical industries with unmatched impact resistance, thermal shock, crush strength, and survivability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalysts and RTO hot exchange applications. Excellent stabilityHigh mechanical strengthResist high temperatures Resistance to thermal shock Resist the corrosion of acid, alkali and some other organic solvents Chinese competitive prices Catalyst Bed Supports RTO hot exchange applications In petrochemical industryIn chemical industryIn fertilizer industryIn natural gas industryIn environment protection
