Abstract—The properties of tar from the high-temperature coking of volatile-rich petroleum coke (CA, coking additive) are compared with the properties of coal tar. According to thermogravimetric data for the residue at temperatures beyond 360°C, the content of high-boiling components is considerably higher for petroleum tar than for coal tar. However, its yield of coke residue is lower than for coal tar. The petroleum tar contains polyaromatic hydrocarbons and heterocyclic sulfur-containing compounds, both of which are also found in coal tar. However, much larger quantities of sulfur-containing quantities are seen in petroleum tar, while the content of individual polyaromatic hydrocarbons is much lower.

挥发性高的石油焦的高温焦化焦油特性

摘要—将富挥发性石油焦（CA，焦化添加剂）的高温焦化后的焦油性能与煤焦油的性能进行了比较。根据温度超过360°C时残留物的热重数据，石油焦油中的高沸点组分含量明显高于煤焦油。但是，其焦炭残渣的产率低于煤焦油。石油焦油包含多芳烃和杂环含硫化合物，这两种油也都在煤焦油中发现。然而，在石油焦油中发现大量的含硫量，而单个多芳烃的含量低得多。
