support media for catalyst:low alumina ball for oil refinery
Product description:
As the material to support and cover catalyst in the reactor ,inert alumina ball can buffer gas or liquids flush on catalyst so as to protect catalyst.It aslo can impove distribution of gas or liquid in the reactor.Therefore,it is widely applied in petrochemical,chemical,fertilizer,gas and enviromental protection industries.
Product Properties
With the characters of high mechanical strength,high chemical stability,and excellent heat endurance ,inert alumina ball can resist high temperature,high pressure ,acid,alkali,salt and vavious organic solvents.
