17%AL2O3 Inert Alumina Ceramic ball - Catalyst Support MediaProduct's Introduction:Ceramic ball,Website:http://www.ksourceltd.com, also known as inert alumina ceramic ball, is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as a supporting material for the catalyst in the reactor and tower packing. Its main role is to increase the gas or liquid distribution point, support and protect the active catalyst with low strength. 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 ball size selectionThe size of the inert ceramic sphere should be chosen according to the size of the catalyst. Usually, 2X rules (or gradients) are used. That is to say, the diameter of the ceramic balls should be twice the diameter of the adjacent catalyst, so that the distribution of the gas flow is most uniform, and the pressure dro is minimized, and the reactor is optimized.Chemical CompositionAl2O3+SiO2Al2O3Fe2O3MgOK2O+Na2O +CaOOther> 93%17-19%<1%<0.5%<4%<1%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 (%)40%Operation temp.(max) (℃)1200Moh’s hardness (scale)>6.5Acid resistance (%)>99.6Alkali resistance (%)>86Crush 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>56※ Other size can be customize.Size and Tolerance (mm)Size3/6/99/1319/25/3850Tolerance±1.0±1.5±2±2.5FAQ
