high alumina ball 99%

Catalyst Bed Support Media 99%High AluminaBall is equal Denstone 99 Support Media. It is in chemical composition99+% alpha alumina and a maximum 0.2wt% SiO2 . Because of its high alumina content and low silica (SiO2 ), it's a very excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed. The XINGFENG 99% High Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1550°C, also it's a good choice for heat retention or equilibration media. For its superior chemical resistance, it's suitable for applications in olefin processes, such as ethylene dryers, where there's the polymerization problem.Chemical compositionAl2O3Fe2O3MgOSiO2Na2OTiO2>99%<0.1%<0.5%<0.2%<0.05%<0.05%Physical propertiesItemValueWater absorption (%)<1Packing density (g/cm3)1.9-2.2Specific gravity (g/cm3)>3.6Operation temp.(max) (°C)1650Apparent porosity (%)<1Size available & Crush strengthSizeCrush strengthkg/particleKN/particle1/8" (3mm)>203>21/4" (6mm)>459>4.61/2" (13mm)>877>8.73/4" (19mm)>1220>121" (25mm)>1630>161-1/2"(38mm)>2340>232" (50mm)>3460>34
