Chinese calcined petroleum coke plants usually produce the following types of petroleum coke:

High-sulfur calcined petroleum coke: This kind of petroleum coke has a high sulfur content and is generally used in ferroalloy production and other fields.

Medium sulfur  calcined petroleum coke: This petroleum coke has a moderate sulfur content and is commonly used in aluminum smelting, steelmaking and other metallurgical industries.

Low-sulfur calcined petroleum coke: This kind of petroleum coke has low sulfur content and is generally used in carbon products, aluminum electrodes, ferroalloy production and other fields. 

needle coke: This petroleum coke has very low sulfur content and is mainly used in the production of high-end carbon products, such as electrode graphite.

The advantages and disadvantages of Low Sulfur Calcined Petroleum Coke are as follows:
Advantage:

Low sulfur content: Compared with high-sulfur calcined petroleum coke, low-sulfur calcined petroleum coke has lower sulfur content, which reduces environmental pollution and reduces corrosion of equipment and products.

High fixed carbon content: Low-sulfur calcined petroleum coke generally has a high fixed carbon content, which allows it to provide long-lasting heat energy in high-temperature environments.

Excellent electrical conductivity properties: Low-sulfur calcined petroleum coke has good electrical conductivity properties, making it suitable for electrode manufacturing and other applications requiring high electrical conductivity.

Disadvantages:

Relatively high cost: Because the production process of low-sulfur calcined petroleum coke requires more stringent handling and processing conditions, its cost is usually higher.

Affected by impurities: Low-sulfur calcined petroleum coke may be affected by other impurities, such as ash, volatile matter, etc., which may affect its quality and stability.

Application areas: Low sulfur calcined petroleum coke is mainly used in the following fields:

Aluminum industry: used as anode char for aluminum electrolysis, providing heat and current.

Steel industry: used as metal reducing agent in steel smelting and steelmaking processes.

Chemical industry: used as raw materials or additives, such as the production of silicon carbide, tempering agents, desulfurizers, etc.

Electrode manufacturing: used to prepare carbon electrodes, suitable for aluminum electrolysis and other electrochemical processes.

Coking plant: used as an energy supply for heating and reduction of raw materials.

Low-sulfur calcined petroleum coke can be used to make anode coal coke, steel, chemical products, electrodes, etc. Its low sulfur content and high fixed carbon content give it certain advantages in environmental protection, thermal energy supply and electrical conductivity properties. However, its higher cost and exposure to impurities need to be considered.
