摘　　要：以甘肃临泽凹凸棒石黏土为载体,MnO2为活性剂,制备脱色剂对碳九(C9)馏分进行脱色。通过正交实验研究了酸度、焙烧温度、活性组分加入量、脱色剂的用量和脱色时间对C9馏分脱色的影响。结果表明,焙烧温度600℃、活化浓度6%、活性组分MnO2含量4%、脱色剂用量8g、脱色时间在60min时,能够使C9馏分的脱色率达到78.66%。Attapulgite clay decolorant was prepared for the decolorization of C9 fraction. Effects of sulphuric acid, calcination temperattre, active component, amount of decolorant and decoloring time on the decolorization of C9 fraction were investigated. Results showed that the decolorant, which was prepared from attapulgite clay treated with 6% sulphuric acid calcinated at 600℃ with the addition of 4% MnO2, has the best decolorization efficiency, and the decolorization rate of C9 fraction can be achieved up to 78.66%.
