Coal tar pitch distilled from by-product coal tar, generated by
metallurgical coke ovens, has strategic importance for the
aluminium industry. The combination of its binding properties with
its high carbon content makes pitch an ideal complement to calcined
petroleum coke for the production of carbon anode paste.
During the past 20 years, the steel industry has migrated from
traditonal points of production in North America and Western Europe
to new emerging markets. The availability of coal tar has mirroed
this shift and has greatly aided in the development of pitch
distillation facilities in the Ukraine and China where Jing Hao has
developed local representation and expertise.
Historically, pitch was supplied in solid form. However, the trend
to liquid pitch continues to grow. Whether transporting pitch in
solid or liquid form, the shipment of pitch requires special
handling, equipment and terminals. This is especially the case for
liquid pitch which must be kept heated at all times.
Definition: The pitch obtained from deep process of coal tar or
general coal pitch.
