一种煤焦油化学预处理剂及预处理方法
摘要：
本发明提供了一种煤焦油化学预处理剂及预处理方法。该煤焦油化学预处理剂是金属盐的醇溶液，其中醇为小分子醇，所述金属盐的醇溶液的质量浓度为5%-50%；优选为30%-50%。本发明还提供了使用上述煤焦油化学预处理剂的预处理方法。本发明所提供的煤焦油化学预处理剂及使用该预处理剂的预处理方法具有脱氮选择性高，与煤焦油中的其它烃类不发生相互作用，预处理损失小的优点。
摘要（英）：

The invention provides a chemical pretreatment agent and a pretreatment method for coal tar. The chemical pretreatment agent for coal tar is an alcoholic solution of a metal salt, wherein the alcohol is a low molecular alcohol and the mass concentration of the alcoholic solution of the metal salt is 5%-50%, preferably 30%-50%. The invention also provides a pretreatment method using the chemical pretreatment agent for coal tar. The chemical pretreatment agent for coal tar and the pretreatment method using the chemical pretreatment agent for coal tar have the advantages of high denitrification selectivity, no interaction with other hydrocarbons in coal tar and less pretreatment loss.
