Activated alumina ball is industrial aluminum hydroxide and bauxite as the main raw material, after scientific formula, grinding into fine powder, rolling into shape and high temperature roasting, has high mechanical strength, long service cycle, good chemical stability, strong adsorption, insoluble in acid and alkali solution, high temperature and corrosion resistance.It can also support, cover and protect the action of the catalyst.Activated alumina ball, mainly used in the reactor catalyst cover supporting material and filling material, packing porcelain ball is mainly used to increase the gas or liquid distribution point, support and protect the strength of the active catalyst is not high.

High aluminum ball has the characteristics of high strength, high chemical stability and thermal stability, high aluminum ball can resist high temperature, high pressure and acid, alkali, salt and various organic solvents corrosion, high aluminum ball is widely used in petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection industries.As the supporting and covering material of the catalyst in the reactor, the high alumina ball can buffer the impact of the liquid and gas entering the reactor to the catalyst, protect the catalyst and improve the distribution of the liquid and gas in the reactor.As the catalyst in the reactor cover support material and column packing.It has the characteristics of high temperature and high pressure resistance, low water absorption and stable chemical properties.Can withstand the corrosion of acid, alkali and other organic solvents and temperature changes in the production process.Its main role is to increase gas or liquid distribution point, support and protect the strength of the active catalyst is not high.

The difference between activated alumina ball and high aluminum ball mainly has the following points:

1, forming temperature is different: activated alumina 300-400℃, high aluminum ball 1300℃.

2, pelletizing process is different: activated alumina is mainly rolled into type, high aluminum ball is divided into rolling into type and pressing molding.

3, the scope of application is not: activated alumina is mainly used for air drying, such as drying machine, pressure swing adsorption, etc., high aluminum ball is mainly used for chemical and petroleum support.
