煤焦油是一種玄色或褐色黏稠狀液體，具備可燃性、消融性、侵蝕性。按密度的差別，分為輕油和重油兩品種型。產量約占裝爐煤的6.2%，其顛末蒸餾、低溫裂解、溶劑萃取等加工體例可獲得苯類、酚類、萘類、高等酚等芬芳族化合物，被普遍用于浩繁產業部分；煤焦油顛末催化加氫后可獲得汽油、柴油等靈活車燃料油。

煤焦油品質目標:水分（W）≤3.0%、密度≤1.07

 

The coal tar is a black or brown viscous liquid,and is characterized by flammability,solubleness and corrosivity.By the specific gravity,it is divided into light oil and heavy oil.Output accounts for 6.2%of coal charging furnace.It can be processed into the aromatic compounds such as benzene,phenols,naphthalenes,higher phenols,etc.by distilling,pyrolysis,solvent extraction,etc.,and is widely applied to various industrial sectors.The coal tar can be made into fuel oils of the motor vehicle such as gasoline,diesel,etc.through catalytic hydrogenation.

Quality Indicator of Coal Tar:

Moisture(W)≤3.0%,Density≤1.07
