| description | The invention discloses an active high silicon pad ball, which is compoed of 50-75% of high silicon clay, 10-40% of coal ash, 3-10% of resin and 5-12% of peeled kaolin, wherein the main chemical components of the active high silicon pad ball are 50-80% of silicon dioxide, 10-20% of aluminum oxide, at most 2% of ferric oxide, at most 2.5% of magnesium oxide and at most 7% of calcium oxide. The coal ash can generate oxidization reaction in high-temperature sintering process, therefore, stuff can form mesh porous structure and the silicon dioxide content in stuff is improved to 50-80% which is 50% higher than the content of silicon dioxide in prior common ceramic ball stuff, thereby improving the oxidation resistance of the stuff. And via the peeled kaolin, the specific surface area of ceramic ball is improved, the dispersion is improved, the absorption ability and activity are improved significantly, therefore, the active high silicon pad ball can be used to replace active carbon and catalyst carrier, which sav |
