Calcined PET Coke, Moisture : 2.25%

petroleum coke for sale.

petroleum coke is the byproduct during the oil refining. It is extracted from the raw oil by the delayed coking.petroleum coke (often abbreviated pet coke or petcoke) is a carbonaceous solid derived from oil refinery coker units or other cracking processes. Other coke has traditionally been derived from coal.this coke can either be fuel grade (high in sulphur and metals) or anode grade (low in sulphur and metals). The raw coke directly out of the coker is often referred to as green coke.in this context, "green" means unprocessed. The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking oven in order to produce anode coke of the desired shape and physical properties. The anodes are mainly used in the aluminium and steel industry. Petcoke is over 90 percent carbon and emits 5 to 10 percent more carbon dioxide (co2) than coal on a per-unit-of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more co2 than coal per unit of weight. The differences between coal and coke in co2 production per unit energy produced are small and depend upon the moisture in the coal (increases the co2 per unit energy -- heat of combustion) and volatile hydrocarbon in coal and coke (decrease the co2 per unit energy).
