α-alumina carrier alpha alumina carrier
Alumina, magnesia, and various composite oxides as the main raw material to produce a variety of ring and cylindrical carrier, including Raschig rings, single hole or porous cylinder, convex porous cylinder, gear single hole or porous cylinder.
Compared with the old craft, the new craft produces the product the appearance size as well as the uniformity of each performance index, thus enhances the processing efficiency (for example: catalyst impregnation efficiency) in the next step, and enhances the overall service life.
α-alumina carrier alpha alumina carrier use and features
Widely used in petroleum and chemical catalysts for the carrier can also be used for catalyst protection agent, adsorbent and so on. The carrier added special additives, with high compressive strength, strong adsorption, porous structure, good thermal stability and so on.
