Supply phthalic anhydride catalyst carrier

Product Introduction phthalic anhydride catalyst carrier for typical magnesia ceramic carrier, add a small amount of high-quality kaolin, adhesives, enhancers, high temperature binder, mineralizing agent, a pore-forming agent, lubricant additives, molding, through a special sintering under high temperature environment. Second, main characteristics anhydride catalyst carrier having a small pressure drop and a favorable energy, per unit volume of a large geometric area, the same thickness of coating download body supporting amount prolong catalyst life and improved catalyst loading; while under the same load, coating thinner, to reduce the diffusion resistance of the product, reducing the depth of the oxidation, improve the selectivity of the catalyst.
