The open ceramic balls
ceramic proppant are a new product based on inert alumina ceramic balls developed by our company. The hole is opened through the axis of the ball diameter. Thus ceramic ball not only has a certain mechanical strength, chemical stability and thermal stability, but also has larger specific area and void ratio, resulting in the increase of the dispersion and throughput of the feedstock and the decrease of system resistance.
The open ceramic balls can be widely used in petrochemical, chemical and natural gas industries, replacing inert alumina ceramic balls as the covering and supporting packing for catalysts.It is proved by the customers that this product can distribute gas and liquid better, compared with the formerly used covering and supporting packing under same operating conditions in the same reactor or furnace.
