高活性吸附剂的制备及性能研究

Research on the preparation of highly active absorbent and performances

以粉煤灰/氧化钙为原料,制备高活性吸附剂,分析了水固比、水合时间、水合温度、添加剂对生成的吸附剂性能的影响。通过测试各试验条件下制备的吸附剂比表面积,表明水和反应制备的吸附剂最佳水固比为20、最优水和反应时间为10～15h,随着温度的升高或在水和过程中增加适量的添加剂,制备的吸附剂比表面积增大,有利于改善吸附剂的吸附性能。

This research is about the preparation of highly active absorbent with fly ash /CaO,then analysis the influences of addictive、 temperature、gas-hydrate time、water-solid ratio on absorbent performances.The influences of experimental parameters on absorbent surface area was invested,the test shows： best water-solid ratio is 20,optimal gas-hydrate time is 10～15h,high temperature and some addictive can increase absorbent surface area,improve its absorbent performances.
