Question

How is coke(fuel) formed? How long does it take to form?

Answer 1

It is formed by the destructive distillation of coal in the absence of air.It takes about 3 to 4 hrs

Answer 2

Coke is a fuel with a high carbon content and few impurities, made by heating coal in theabsence of air. It is the solid carbonaceous material derived from destructive distillation of low-ash and low-sulfur bituminous coal. ... While coke can be formed naturally, thecommonly used form is synthetic.




about 300 million years

Fossil fuels are formed from the remains of ancient organisms. Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource. The conditions that would eventually create coal began to develop about 300 million years ago, during the Carboniferous period
