Carbonization of dead plants yields

Carbonization of dead plants yields coke.
The process by which dead vegetation is slowly converted into coal is known as carbonization. Applications of coke can be observed in the steel manufacturing industry and mineral extraction. 

In addition, petrol, natural gas, and petroleum gas are obtained from petroleum refining. Carbonization of dead plants requires temperature more than $280^{o}C$. At this temperature, wood is broken into charcoal.
