Theparticles of YSseries of silver catalysts are hollow cylindrical shape with seventhrough-holes (1.0 to 2.5 mm in diameter), and with an external diameter of 7.0to 9.5 mm and a length of 7.0 to 9.0 mm. The desired particlesize of silver catalysts can be modified according tothe operational parameters of the reactors in EO/EGunits.

Bulk density: 800±100 kg/m3

Silver content: 17% to 30% (wt%)

Wear rate: ≤10% (wt%)
