It is an ideal support media.Owing to its unique structure enables an upper support layer with a typical diameter of 11.5 mm to effectively retain a bed of 1.6 mm catalyst without any migration into the support layer. This eliminates the need for micro-sized spherical support balls, reduces the number of support layers needed, reduces pressure drop and increases the space available for catalyst or adsorbent in the process reactor. In addition, Wave type shape ensure sufficient gaps between the packings to promote air’s freedom flow. Also overcome packig bed’s unevenly heat destribution phenomenon happening.
