摘　　要：以茂名油页岩渣为原料,利用碱离解法制备白炭黑。考察了碱离解温度、碱离解时间、碱浓度、原料煅烧温度和原料煅烧时间等各种因素对SiO2产品浸出率的影响规律。最佳工艺条件为:碱浓度3.3 mol/L、碱离解时间3 h、碱离解温度70℃、煅烧温度900℃、煅烧时间4 h,该条件下白炭黑的产率可达16%,白炭黑白度为92。White carbon black was prepared by alkali dissociation respectively from oil shale ash. The effects of synthesis condition on the leaching rates of white carbon black were also investigated. The results showed that the optimal synthesis conditions of white carbon black were 3.30 mol/L NaOH, dissociated at 70 ℃ for 3 h, calcining temperature 900 ℃, calcining time 4 h, and leaching rate was amount to 16% and whiteness was 92.
