摘　　要：在实验室研究了聚丙烯腈基活性碳纤维（ Ｎ Ａ Ｃ Ｆ）的制备条件，如活化温度、活化时间对静态吸附脱除汽油中硫醇的影响。结果表明，活化温度在 ８００ ℃以上和活化时间在９０ ｍ ｉｎ 以上制得的 Ｎ Ａ Ｃ Ｆ 可直接用于吸附催化裂化汽油中的硫醇，使其硫醇硫含量降到 １０ μｇ／ｇ 以下。负载钴盐后的 Ｎ Ａ Ｃ Ｆ也可脱除汽油中的硫醇，与不负载钴盐相比，对汽油脱硫醇的效果稍有增大。在液固比为 ４ ０００（ｍ Ｌ∶ｇ）的条件下，可使汽油中的硫醇硫含量由９１．７ μｇ／ｇ 降到４．５ μｇ／ｇ。The influence of the preparation conditions of polyacrylonitrile based activated carbon fiber (NACF), such as activated temperature and time on its adsorbing behavior towards thiols in gasoline was studied. The NACF was prepared at an activated temperature higher than 800℃ and an activated time longer than 90 minutes. The test result showed that it can reduce the content of thiol sulfur in FCC gasoline to lower than 10μg/g. The effect of dispersion of appropriate cobalt salt on NACF was better than the NACF without cobalt salt.
