Raschig rings are usually small cylindrical or tubular structures made of a variety of materials such as ceramics, metals or plastics. They are stacked inside a column or tower to create a large surface area for contact between gas and liquid phases. When the structure of the alumina carrier is raschig ring, it is called raschig ring alumina carrier. The carrier can be used in drying tower, absorption tower, scrubbing tower, regeneration tower in chemistry, metallurgy, oxygen generation, etc.
γ-Al2O3 or θ-Al2O3
Our HGRR type raschig ring alumina carrier can be used as a covering proppant and adsorbent material for catalysts in reactors. Its main function is to increase the distribution point of gas or liquid, support and protect the active catalyst with low strength. It has the characteristics of high purity, good heat resistance, good mechanical shock resistance and stable chemical properties. HGRR type raschig ring alumina carrier can be widely used in petrochemical, natural gas, coal chemical and other industries.
Our HGRR type raschig ring alumina carrier is non-toxic, tasteless, odorless, and insoluble in water and ethanol. In addition, it can be used as both a catalyst and a catalyst support.
