一种脱除煤焦油中金属和灰分的复合剂及其使用方法
摘要：
本发明公开了一种脱除煤焦油中金属和灰分的复合剂及其使用方法，以克服现有技术中脱金属剂用量大、脱除率低和官能团有限等问题。该复合剂由40～70％活性剂、15～35％增效剂、5～15％沥青胶质分散剂、1～10％缓蚀剂和5～20％助剂组成，百分含量以复合剂总重量计。该脱除煤焦油中金属和灰分的复合剂适用于煤焦油预处理及深加工技术，使用本发明复配剂和方法，复配剂用量少、脱除效率高、制备工艺简单，并且使用方法方便。
摘要（英）：

The invention discloses a complexing agent for removing metal and ash in coal tar and a use method thereof. The problems that in the prior art, the use amount of a demetallization agent is large, the removal rate is low, and functional groups are limited are solved. The complexing agent is prepared from, by weight, 40%-70% of active agent, 15%-35% of synergist, 5%-15% of pitch colloid dispersant, 1%-10% of corrosion inhibitor and 5%-20% of auxiliary. The complexing agent for removing metal and ash in coal tar is suitable for the fields of coal tar pre-treatment and deep processing. By means of the complexing agent and the method, the use amount of the complexing agent is small, removal efficiency is high, the preparation process is simple, and the use method is convenient.
