铝电解生产中，碳素阳极两组分(石油焦和沥青结焦)的活性差异带来阳极的选择性氧化，是造成碳素阳极过量消耗的主要原因之一。

Selective oxidation of carbon anode in aluminum electrolysis caused by reactivity difference between pitch coke and petroleum coke is one of the main causes for excess carbon consumption.

随着改质沥青的加入，焦2煤和1/3焦煤的胶质层厚度显著增加，焦2煤的粘结性指数也显著增加。

The plastometer thickness of No. 2 coking coal and 1/3 coking coal increased dramatically by adding modified coal tar pitch, meanwhile, the coal caking indexes increased dramatically.

初步探讨了活化剂的加入对煤沥青的焦化活性、沥青焦的结构、氧化活性和导电性的影响。

Both the oxidation resistance and the electrical conductivity of the pitch coke can be improved when a suitable amount of activating agent is added in the coal tar pitch.
