煤焦油 为煤干馏过程中所得到的一种液体产物。 高温干馏(即焦化)得到的焦油称为高温干馏煤焦油（简称高温煤焦油），低温干馏（见煤低温干馏）得到的焦油称为低温干馏煤焦油（简称低温煤焦油）。两者的组成和性质不同，其加工利用方法各异。 高温煤焦油 黑色粘稠液体，相对密度大于1.0,含大量沥青,其他成分是芳烃及杂环有机化合物（表1）。包含的化合物已被鉴定的达 400余种。工业上将煤焦油集中加工，有利于分离提取含量很少的化合物。加工过程首先按沸点范围蒸馏分割为各种馏分（表2），然后再进一步加工。各馏分的加工采用结晶方法可得到萘、蒽等产品；用酸或碱萃取方法可得到含氮碱性杂环化合物（称焦油碱），或酸性酚类化合物（称焦油酸）。焦油酸、焦油碱再进行蒸馏分离可分别得到酚、甲酚、二甲酚和吡啶、甲基吡啶、喹啉。这些化合物是染料、医药、香料、农药的重要原料。煤焦油蒸馏所得的馏分油也可不经分离而直接利用，如沥青质可制电极焦、碳素纤维等各种重要产品，酚油可用于木材防腐，洗油用作从煤气中回收粗苯的吸收剂，轻油则并入粗苯一并处理。 低温煤焦油 也是黑色粘稠液体，其不同于高温煤焦油是相对密度通常小于1.0，芳烃含量少,烷烃含量大，其组成与原料煤质有关（表3）。 低温干馏焦油是人造石油的重要来源之一，经高压加氢制得汽油、柴油等产品。
