Abstract

At PAO Koks, an organic additive is produced by the thermal solution of coal in the laboratory. Its influence on the quality of metallurgical coke is investigated. The additive is produced from G coal concentrate, using the anthracene fraction of coal tar as the solvent. On introducing 5–10% of the additive in place of G coal, the strength CSR of the coke after reaction with CO₂ is increased, and its reactivity CRI is decreased. The sulfur content is lower in the new additive than in petroleum additives.

摘要

在 PAO Koks，一种有机添加剂是在实验室中通过煤的热溶液生产的。考察了其对冶金焦质量的影响。该添加剂由G煤精矿生产，以煤焦油的蒽馏分为溶剂。加入5-10%的添加剂代替G煤后，焦炭与CO _{2反应后的强度}CSR增加，反应性CRI降低。新添加剂的硫含量低于石油添加剂。
