99%AL2O3 Inert Alumina Ceramic Ball - Catalyst Support MediaProduct's Introduction:Ceramic balls, also known as inert alumina ceramic balls, are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as auxiliary materials for catalysts in reactors and column packing. Its main role is to increase the distribution point of gas or liquid to support and protect low-strength active catalysts. According to the AL2O3 content of inert alumina ceramic ball, ceramic balls are divided into: ordinary ceramic ball, inert alumina ceramic ball, medium aluminum ceramic ball, high aluminum ceramic ball, 99 alumina ceramic ball, open-hole ceramic ball, micro-porous ceramic ball, regenerative ceramic ball, etc.Inert alumina ceramic balls are characterized by high temperature resistance, high pressure resistance, low water absorption and stable chemical properties. It withstands the corrosion of acids, bases and other organic solvents and withstands the temperature changes that occur during production. Due to its excellent stability and reliability, it is the most widely used package in the world. Made of high-quality chemical porcelain clay material, it has excellent stability, high mechanical strength and thermal shock resistance. It is an ideal choice for various catalysts.Inert alumina ceramic ball size selectionThe size of the inert ceramic ball should be selected according to the size of the catalyst. Generally, the 2X rule (or gradation) is adopted. That is, the diameter of the ceramic ball should be twice the diameter of the adjacent catalyst, so that the distribution of the gas flow is the most uniform, and the pressure drop is minimal, the reactor is optimized.Chemical CompositionAl2O3+SiO2Al2O3SiO2Fe2O3MgOK2O+Na2O+CaOOther> 92%23-26%68-73%<1%<2.5%<4%<0.5%Leach able Fe2O3 is less than 0.1%Physical PropertiesItemValueWater absorption (%)<0.5Bulk density (g/cm3)1.35-1.4Specific gravity (g/cm3)2.3-2.4Free volume (%)40Operation temp.(max) (℃)1100Moh’s hardness (scale)>6.5Acid resistance (%)>99.6Alkali resistance (%)>85Crush StrengthSizeCrush strengthKg/particleKN/particle1/8''(3mm)>35>0.351/4''(6mm)>60>0.603/8''(10mm)>85>0.851/2''(13mm)>185>1.853/4''(19mm)>487>4.871''(25mm)>850>8.51-1/2''(38mm)>1200>122''(50mm)>5600>56Size and Tolerance (mm)Size3/6/99/1319/25/3850Tolerance±1.0±1.5±2±2.5Packaging & ShippingFAQ
