煤焦油是一種黑色或褐色粘稠狀液體，具有可燃性、溶解性、腐蝕性。按密度的不同，分為輕油和重油兩種類型。產量約占裝爐煤的6.2%，其經過蒸餾、高溫裂解、溶劑萃取等加工方法可得到苯類、酚類、萘類、高級酚等芳香族化合物，被廣泛用于眾多工業部門；煤焦油經過催化加氫后可得到汽油、柴油等機動車燃料油。

煤焦油質量指標:水份（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
