| description | 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. |
