By Noah Beecher Kelk Metallurgical coal also called metcoal or coking coal is a type of coal that is used in the production of steel It is of a higher purity than thermal coal which is used in energy generation To make steel metcoal is heated at around 1100 degrees C to remove water and other chemicals This is done without the presence of oxygen The result is a lump of near pure carbon

DELAYED COKING PROCESS Description Delayed coking process is a thermal process which increases the molecular aggregation or association in petroleum based residues or coal tar pitches leading to extended mesophase domains This is achieved by holding them at an elevated temperature usually 750 K–765 K over a period of time 12 to 36 h
Metallurgical coal also known as coking coal is a low sulfur low ash and low phosphorus grade of coal It is used to produce high grade coke which is an important reactant for manufacturing of primary steel in the blast furnace process
