65% Ceramic Ball
Products Description
65% ceramic balls serve as covering media, proppant and protective agent for catalysts or adsorbents in chemical process equipment. It is usually called inert alumina ceramic ball in the industry, because its chemical composition is stable, and it will not participate in chemical reaction changes. It is precisely because of this that it avoids its reaction deposition on the catalyst bed, causing catalyst blockage, burning or even poisoning the catalyst.
65 Alumina ball Support Media has very excellent thermal properties, with its high density high-temperatur resistance 1450℃, also it's a good choice for heat retention or equilibration media.
Super Packing Mall alumina ball has high mechanical strength, high pressure resistance, and long service life; good high temperature resistance, high temperature resistance; good chemical stability, corrosion resistance to acids, alkalis, salts and various organic solvents, and does not chemically react with materials.
It is especially suitable for high and low temperature conversion furnaces, reforming furnaces, hydroconverters, desulfurization tanks and methanation furnaces in fertilizer and methanol plants. It plays the role of dispersing vapor and liquid, supporting, covering and protecting catalysts. It can also be used in the steel industry. In hot blast stoves and heating conversion equipment.
