Coke (fuel)

Metallurgical coke sounds like a soda beverage, but it's not. It is a refined carbon product made from a special kind of coal. Using extremely high temperatures, coal can purified into coke -- which is then used in the iron and steel making processes. One of the most important steps in the coke-making process is ...

Petroleum Coke

Calcined Petroleum Coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw "green" petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F).

Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final crackingprocess—a thermo-based chemical engineering process that splits long chain hydrocarbons of ...

Petroleum Coke Calcining Systems

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Oxidation of coke with petroleum

Petroleum Coke General Properties: Volatile Combustible Matter (VCM) • VCM is unconverted pitch – Target 12% Max, fuel coke 9% to 10% – 14% VCM is very high; Coke will be soft • Increases green coke hydrogen content • Rules of thumb for control in fuel coke – Increase heater outlet 5-7 °F for 1% decrease in VCM

The Creation of Petroleum Coke

The properties of coking batch may be stabilized by means of DK coking additive based on the products of petroleum pyrolysis, characterized by low ash content (Ad = 0.4%), high sulfur content (Std= 4.1%), and high yield of volatiles (Vdaf = 17.2%) relative to coal concentrates. Individual coking of DK coking additive yields a product (particle size >40 mm) with postreactive strength CSR = 77 ...
