Application of inert alumina ceramic ball
Inert alumina ceramic ball has the characteristics of high mechanical strength, long service life, good chemical stability, no chemical reaction with materials, high temperature resistance, high pressure resistance, strong acid and alkali corrosion resistance, and good thermal shock stability.
Because the chemical nature of the inert porcelain ball is relatively lazy, it obviously does not undergo chemical reactions throughout the reactor. Use a carrier to cover the catalyst without changing the catalyst. The gas or liquid in the reactor has a temperature. The filling above the ceramic ball prevents the gas or liquid from blowing directly to the catalyst, which has a protective effect on the catalyst control. The shape of the porcelain ball is conducive to the uniform distribution of gas or liquid. Promote a more complete chemical reaction.
The main function of the filled ceramic ball is to increase the distribution point of gas or liquid, and support and protect the active catalyst of chemical materials with low strength. It is mainly used in the high-temperature, high-pressure, corrosive working environment of the chemical industry, in the petroleum, chemical industry, reformers, reactors, packing towers to prevent the equipment covered by the filtered silica or form fouling or damage the catalyst carrier.
Filler ceramic balls are also commonly used in high and low temperature converters, converters, hydroconverters, desulfurization tanks and converters in chemical fertilizer plants and hot blast stoves and heating conversion equipment in the iron and steel industry. The application field is very wide.
