The fossil fuel especially coal is a major energy source. It is converted to differentforms of energy by controlled technologies like coal carbonization, liquificationand hydrocarbonation.
Coal carbonization processes, namely producer gas production
(400 to 500 °C), low temperature carbonization (LTC, 600 to 700 °C) and
high temperature carbonization (HTC 900 to 1100 °C) are employed to produce
coke, tar and gases for different uses.Coke making had been one of the major pursuits of CFRI since inception.
Fundamental research on coal science and the carbonisation process found
its applications in the development and transfer of various technologies
on HTC coke, formed coke, briquettes, soft coke at different point of
time. Keeping in view the gradual depletion of indigenous good
quality coking coal resources , R&D initiatives at CFRI provided the
scientific basis and scope of utilising different type inferior grade coals
as blend components for metallurgical coke making. Application of
the knowledgebase backed by validation tests in pilot plants has
helped in optimising the blend components for various steel plants
utilising both indigenous and imported coals.
