摘要
考察了炭化温度对流化床飞灰制活性焦性能的影响 实验表明 :炭化温度的高低对成型活性焦的性能有很大的影响 在满足其它性能的前提下 ,炭化温度的最佳范围为60 0℃— 70 0℃ ,在此条件下制得的活性焦其强度大于 95 % ,硫容为 80mgSO2 ·g- 1 ,碘值大于 5 5 0mgI·g- 1 ,收率约为 42 % 。
Active coke for SO 2 removal in flue gas was prepared from fly ash. Effects of carbonation temperature on properties of active coke were investigated and the results showed that carbonation temperature was a important factor, which could affect BET surface area,micropore area and volume, yield, hardness,sulfur capacity and other properties of active coke. The optimal carbonation temperature range was 600℃-700℃,under which condition, active coke prepared could meet the requirements for desulphurization.
