Petroleum Coke High Carbon is an essential raw material for the production of Steel. It is a more eco-friendly and energy-efficient alternative to coal in iron ore melting processes, such as blast furnaces. In this post, we explain how high carbon PETCOKE can be used for improving steel quality and reducing environmental impacts during industrial processes.
Petroleum coke is the carbonization by-product of high boiling hydrocarbon fractions obtained from oil processing. It is primarily made of carbon, but also contains hydrogen, oxygen nitrogen sulfur, and metal elements, such as nickel and vanadium. The physical characteristics of petroleum coke vary depending on the type and production process. It is available in different shapes and sizes, including blocky, needlelike or as small shots. It can either be calcined of uncalcined. The density is high for calcined petrol coke and low for uncalcined.
The term metallurgical coke refers to a coal-based fuel that is porous and grey with a high level of carbon. This is the result of thermally treating coal or coal blends in order to remove volatile compounds. Iron ore is smelted in blast furnaces with it. It can also be used as fuel for stoves, forges and other appliances. Majority of metallurgical Coke is used during iron ore smelting in order to produce pig-iron. It is a valuable byproduct of oil refineries and has several advantages over coal as an energy source.
In iron making processes, such as direct reducton, the use of petroleum coal reduces or eliminates the formation slag from the hot liquid metal. The combustion of petroleum coal produces high-quality carbon monoxide reducing gasses that are very effective in improving the strength and quality of direct reduced metal.
The production of direct reduced steel is the most common use for metallurgical ore coke. This process involves melting the iron ore under a reducing atmospheric atmosphere, adding coke to it and then oxidizing these oxides to create steel. This process exposes the iron and coke to extreme pressure and heat, resulting in very durable and strong steel products.
Petroleum coke is not only a great carbon source, but it's also a good insulator and heater. The insulating properties of petroleum coke allow higher process gas temperatures to be used during the reduction of the iron, increasing productivity and resulting in better quality, stable direct reduced iron.
The physical properties of petroleum coal are affected by its type, production method and impurities. You can test them using different physical methods, such as gas adsorption, drainage and resistivity. The pore structure in petroleum coke can influence its adsorption capacity and reaction activity. Different types have different pore structures, which can be more porous, softer or harder, or more isotropic.
