Naftasaadus

Naftasaadus, also known as petroleum coke, is a carbonaceous solid material derived from the coking process of crude oil or petroleum fractions. It is primarily composed of carbon and hydrogen, with trace amounts of sulfur, nitrogen, and other elements. The coking process involves heating crude oil or heavy petroleum fractions in the absence of air to high temperatures, typically between 450°C and 550°C. This process converts the liquid hydrocarbons into a solid coke and various gaseous by-products.

Naftasaadus is a valuable by-product in the petroleum industry, particularly in refineries that produce large quantities of heavy oil fractions. It has several applications, including:

1. Fuel: Due to its high carbon content, naftasaadus can be used as a fuel in power plants and other industrial applications.

2. Anode material: It is used in the production of aluminum through the Hall-Héroult process, where it serves as an anode.

3. Carbon electrodes: Naftasaadus is used in the production of carbon electrodes for electric arc furnaces and other high-temperature applications.

4. Chemical feedstock: It can be used as a feedstock for the production of various chemicals, such as carbon black and synthetic graphite.

The properties of naftasaadus can vary depending on the source of the crude oil and the specific coking process used. However, it generally has a high calorific value, a low ash content, and a high carbon content, making it a desirable material for various industrial applications.
