Product Description

Product Description

MID-Alumina Ceramic Ball

Products introduction:

MID-Alumina Ceramic Balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as the covering support material and tower packing for the catalyst in the reactor. It has the characteristics of high temperature and pressure resistance, low water absorption and stable chemical properties. It can withstand the corrosion of acids, alkalis and other organic solvents, and can withstand temperature changes during the production process. Its main function is to increase the gas or liquid distribution points, support and protect the active catalyst with low strength.

Application:
They are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers.
