Complaint
The alumina filler ball is made of alumina ultrafine powder as the main raw material through molding process and high-temperature tunnel kiln firing. It has the characteristics of high temperature resistance, high pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of strong acid-base and other organic solvents, has good thermal shock performance and can adapt to different temperature changes. It is mainly used in high temperature, high pressure and corrosive working environment in petrochemical industry. It is an ideal filler in reformer, reaction furnace and packed tower in petrochemical industry.
Application fields:
Used in petrochemical industry as packing ball and catalyst carrier of packed tower; It is used as bottom filling materials for hydrogenation and refining units, catalyst reforming units, isomerization units and demethylation units in oil plants, chemical fiber plants, alkylbenzene, ethylene plants and natural gas plants.
