Alumina Inert Packing Balls
Introduction
Alumina inert packing ball are made of alumina ultrafine powder as the main raw material, using advanced molding technology and high temperature tunnel kiln firing. Alumina filled balls have higher. High strength, high temperature resistance, high pressure resistance, low water absorption rate, strong acid and alkali corrosion resistance, good thermal shock performance, good chemical stability and other characteristics.
Application
Alumina inert packing balls mainly used in petroleum, chemical industry and other industries as tower packing ball, catalyst carrier, used in the petrochemical industry high temperature, high pressure, corrosive working environment, is the majority of petroleum, chemical industry in the conversion furnace, reactor, packing tower more ideal packing, For petrochemical plants, chemical fiber plants, alkylbenzene, vinyl plants, natural gas plants and other hydrogenation refining plant, catalytic reforming plant, isomerization plant, demethylating plant as the base filling material.
It is used as support covering material and column packing for catalyst, molecular sieve, desiccant, etc. in the reactor. Its main role is to increase the distribution of gas or liquid, support and protect the strength of the active catalyst is not high.
Advantages
Alumina filler ball (inert porcelain ball) high temperature, high pressure, chemical properties of stable characteristics, can withstand strong acid and alkali and other organic solvent corrosion, and can adapt to different temperature changes.
