Coke is produced by
Pulverizing coal in inert atmosphere
Heating wood
in a limited supply of air at temperatures below 3000c
Strongly
heating coal in the absence of air in a closed vessel
Binding the
pulverized coal into briquettes
Strongly
heating coal in the absence of air in a closed vessel
●Coke is
produced by heating coal at high temperatures in absence of oxygen,
for long periods of time. This heating is called thermal distillation or
pyrolysis.
●In order to
produce coke that will be used in blast furnaces, coal is usually
thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.
●Coke is the
residue of coal left after destructive distillation and used as fuel.
Hence, the
correct option is (C).
