Product Technology: The carrier is jointly developed by Liming Chemical Engineering Research Institute and a technical institution of an aluminum corporation, and the production process is broken down at different places. It uniformly mix boehmite、nitric acid and adhesive into wrought material, extrusion forming by spiral crowded strip machine, get strip active aluminum oxide carrier via drying、roasting. Then catalyst can be made by adding palladium into carrier. Its shape is cylindrical long strip.

 Production Scale: 300t/year

Product Usage: It is widely used in catalytic hydrogenation、absorptive removal fields of chemical industry、medical industry、environmental protection, such as anthraquinone hydrogenation in the hydrogen peroxide production、desulfurization、olefin de-acetylene、gas de-oxy purification.
