Abstract
The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.
