Quick Details
Specifications
99% AL2O3 alumina filler balls very low silicon content is made of alumina powder. Its high purity and high strength make it a very high temperature for the reaction tower in the good to avoid the leaching of silica covered the formation of downstream equipment or dirt or poison the catalyst carrier.
Inert alumina ceramic ball is widely used in petrochemical plants, chemical plants, alkyl benzene plants, aromatic plants, ethylene plants, natural gas plant hydrocracking unit, refining unit, catalytic reforming unit, isomerization unit, from a Bottom of filler material based devices. It has a high temperature high pressure, low water absorption, chemical stability characteristics. Can withstand acids, alkalis and other organic solvents and can withstand the temperature of the production process changes occur. Its main role is to increase the gas or liquid distribution points, support and protect the strength of the active catalyst is not high.
I plant the special specification according to user needs or special requirements, users can also be drawing production, and carefully designed for users. Easy ordering, fast delivery, consignment agent, to implement three users are welcome to visit.
