Petroleum coke, also called
petcoke
, is a rocklike leftover of the oil refining process. Energy can be created from petroleum coke, so it is often turned into dry cells and fuels based on the type of coke it is. There are several classifications of petroleum coke, and each one is used to create different substances.
Calcined petroleum coke is made when petroleum coke is calcined, or roasted, just below the melting point. This coke is commonly used in the smelting industry for the creation of metals such as titanium, aluminum and steel. This is because calcined coke is used as an anode to produce these metals.
The largest single nonfuel use of petroleum coke is in the manufacture of carbon anodes for the aluminum smelting industry which accounts for almost 80 percent of all petroleum coke produced.

What are the pros and cons of using petroleum coke?
Petroleum coke is cheaper than coal; therefore, the economics of the process can be improved by substituting coke for coal. Petroleum coke cannot simply be substituted 100% for coal due to hardness issues and combustibility issues. Usually an existing plant may use petroleum coke as a 20% substitute for existing coal use. This results in problems. Now your workers have to handle both coal and coke separately and ensure the intended blend ratio is maintained in order to maintain operability. There are specific materials handling issues than can make the discount less advantageous than is immediately apparent. Equipment such as cranes, conveyors, and crushers may frequently break down and may need to be spared in order to keep the process running. Also if the source of the petroleum coke is not locally available supply disruptions may occur based on price changes in petroleum coke (or in bunker fuel or marine diesel oil (MDO) which is used by the ships that carry coke). For instance shipping petroleum coke from the United States to China is only economical when petroleum coke is above a certain price is China. Petroleum coke may also increase the SOx (sulfur dioxide or sulfur trioxide) emissions from the plant. Options to mitigate the emissions impact include buying higher priced, lower sulfur coal and/or coke to blend into the fuel mix. This negatively affects the economics of the original planned coke substitution. In the case of a grassroots project designed to burn petroleum coke (such as a circulating fluidized boiler, (CFB) ), the economics can be much more favorable. Even in this case environmental permitting issues and petroleum coke supply issues should be evaluated before starting the project. Due to recent concerns with carbon dioxide regulations and ever more strict sulfur emissions regulations, permitting solid fuel boilers has become more difficult throughout the world; however, the economics of using petroleum coke can still pay off depending on the required payback period of the project.

In what goods does the petroleum and coal products industry specialize?
Products in this industry include calcined petroleum coke, regular petroleum coke, fireplace logs, fuel briquettes, or petroleum waxes, independently of petroleum refineries.
Is petroleum coke the same as carbon blank?
No, Petroleum coke is not same as carbon black because carbon black is the product of incomplete combustion of petroleum products
What is coke in petroleum?
Petroleum coke (Pet coke or petcoke) is a carbonaceous solid that is derived from oil refinery coker units or other cracking processes. It is over 90% carbon.

What is the residue which is not recovered in distillation process of gasoline?
You think probable to petroleum coke.
Is petroleum coke the same as petroleum gas?
No. Petcoke (petroleum coke) looks like coal and can be burned in coal boilers with little adjustments. The difference lies in the composition and production: coal has less carbon contents, more ash and usually less sulfur. Coal is also obtined in mines while petcoke is the resulting residue of petroleum processing.
How is a carbon black briquette made?
most are made by pressing petroleum coke in a mold.
Is graphite found in the US?
Yes, there are some very large reserves of graphite in the US. However, graphite is no longer mined in the US because graphite can be synthetically produced using petroleum coke. Petroleum coke is much more pure and economic form of graphite.
Examples of fuels?
Coke, petroleum, radioactive elements ... etc..
Is pet coke a hazardous material?
Yes. Gasoline is regulated as a hazardous material (flammable liquid) in transportation. Gasoline is a flammable substance and it can harm your health if you have a substantial enough exposure to it.
