Coal tar production

1. Production of Coal Tar on
Industrial Scale

2. What is Coal Tar?
 Coal Tar is a brown
black liquid of extremely
high viscosity.

3. How Coal Tar Derived
 It is a by-product obtained during the
carbonization of coal to make coke.
 It is also derived from the gasification of coal
to make coal gas.

5. Carbonization of Coal
 The coke production involves the process of
coal carbonization at high temperature (1100
˚C) under the oxygen deficient environment to
concentrate the carbon.
 The commercial carbonization process is
categorized into two processes:
 By-product Coke production
 Non-Recovery/ Heat Recovery Coke production

6. Cont….
 In By-product coke production process Coal tar
is obtained as a by-product.
 While in Non-Recovery Coke making process no
by-products are recovered.

8.  The process of By-Product Coke production comprises
of different steps which are as follows:
 Step-1: Before carbonization, the selected coals from
specific mines are blended, pulverized, and oiled for
proper bulk density control.
 Step-2: The blended coal is charged into a number of slot
type ovens wherein each oven shares a common heating
flue with the adjacent oven.
 Step-3: Coal is carbonized in a reducing atmosphere and
the off-gas is collected and sent to the by-product plant
where various by-products like coal tar, light oil, etc. are
recovered.
