alumina ball

These products are made from Alpha alumina that has a very low silica content. The high purity and strength make this an ideal choice for high temperature and stream applications where it is necessary to avoid the problems of leached silica coating downstream equipment or fouling or poisioning the catalyst bed.Other qualities forACICHEMSHUN CBS-99A are:Monolith structure eliminates in-service spalling and delamination, which prevents the incidence of fine chips and splinters plugging beds of catalyst. Maximum resistance to erosion and low attrition minimizes the possibility of catalyst contamination High thermal shock resistance Applications forACICHEMSHUN CBS-99A:Ammonia production: herewith temperatures can reach 1250 with pressure as high as 3500kpa Methanol and hydrogen production: primarily reforming Alkylation process using hydrogen fluoride at high temperatures Naphtha reforming Isomerization Chemical composition of Ceramic ball 99ASiO2Fe2O3Al2O3TiO2CaOMgOK2ONa2O0.14%0.05%>99%0.017%0.001%0.001%0.04%0.39%Physical properties of Ceramic ball 99AItemValueWater absorption<5%Packing density (MT/m3)1.8-2.0Specific gravity3.0-3.5Operation temp.(max)1600Apparent porosity,%<5%Crush strengthkg/particleKN/particle1/8(3mm)>203>21/4(6mm)>459>4.61/2(13mm)>877>8.73/4(19mm)>1220>121(25mm)>1630>161.5(38mm)>2340>232(50mm)>3460>34
