Inert ceramic balls, catalyst support media

タイトルまたは説明

Inert alumina ceramic ball is not susceptible to chemical reactions, and its inherently dense texture, very low water absorption, does not act as a drying agent.

Inert alumina ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries as a covering support material and tower packing for catalysts in the reactor.

Most of them are bottom-filling materials such as chemical fiber plant, alkylbenzene plant, aromatics plant and other hydrocracking refining equipment, catalytic reforming equipment, isomerization equipment, and demethylation equipment.

The inert alumina ceramic ball is prepared by superfine calcined alumina micropowder as a raw material, uniformly mixed and mixed by a fully automatic mixing device, formed into a ball machine and calcined at a high temperature tunnel kiln at ***0 °C.

Inert alumina ceramic ball is resistant to high temperature and pressure, low water absorption, stable chemical function, acid, alkali and other solvents, and can compensate for temperature changes during production, and has good thermal stability.

Inert ceramic ball also has proven performance of thermal shock resistance (They can stand the change in temperature during the manufacturing process.)

The main application of inert ceramic balls is to increase the distribution spots of gas or liquid in a reactor, and to support and protect the activating catalyst with low strength.

Alumina ceramic balls are mainly used as proppants, so there is a need for compressive strength, water absorption, and abrupt changes in temperature.

Taking *9% φ*0mm alumina filler ball as an example, its compressive strength is about *3KN/piece, water absorption is less than 5%, bulk density is ≥***0kg/m, temperature resistance is >**0°C, and it is used as a material for filling the bottom. Has the advantage of acid and alkali corrosion resistance.

The index data of inert alumina ceramic balls are inseparable from the alumina content.
Generally, the higher the alumina content, the better its performance, and the higher the price, which needs to be selected according to the specific needs of users.

Inert alumina ceramic balls are widely used in many fields, including petrochemical, chemical engineering, fertilizer production, natural gas and environmental protection.

We design and make a full range of inert ceramic balls, alumina content is from *8% to *9.5% and size available: **1mm, **3mm, ***0mm
