摘要(Abstract)：

为了将油渣气流床气化后的副产炭黑进行资源化利用，以油渣气化副产炭黑为原料酸洗降灰后(SCB)掺杂玉米淀粉，经KOH活化法改性成中孔活性炭(SAC)，研究玉米淀粉掺杂量对活性炭样品微观结构的影响机制;借助亚甲基蓝染料废水检测其吸附性能，考察质量、浓度、时间、温度等因素对样品吸附亚甲基蓝染料废水的影响。结果表明:SAC-3样品(m(SCB)∶m(KOH)∶m(玉米淀粉)=1∶4∶0.75)具有较好的孔结构和吸附效果，比表面积达到606.01 m~2·g~(-1)，孔容为0.74cm~3·g~(-1)，碘吸附值为951.27 mg·g~(-1)，且具有以介孔为主的丰富孔隙结构以及含氧官能团(C=O、C—O、O—H);在实验范围内，优选的活性炭用量为0.04 g、亚甲基蓝初始质量浓度为200 mg·L~(-1)、吸附时间为30 min、吸附温度为25℃的条件下，SAC-3对亚甲基蓝溶液的吸附效果最佳，清除率为94.54%，吸附量为472.71 mg·g~(-1)，达到市售活性炭的2倍左右。研究结果为油渣气流床气化后副产炭黑的资源化利用提供了理论指导。
