Submit Your Answer
Explanation: Carbonization carried out at a low temperature (between 500 degrees C and 700 degrees C). During the process, the smoke-producing compounds are driven off as tars and oils and collected as valuable byproducts, leaving a coke with about 10% volatile matter.
During this process, the fuel is broken down into solid residue called semicoke, a primary gas and a watery condensate.
