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 Medium Sulfur Calcined Petroleum Coke are as follows:

Advantage:

Relatively low sulfur content: Compared with high-sulfur calcined petroleum coke, medium-sulfur calcined petroleum coke has a lower sulfur content, which reduces the degree of environmental pollution.

Some degree of low cost: Medium-sulfur calcined petroleum coke is relatively low-cost to produce, making it an affordable option.

Disadvantages:

Lower fixed carbon content: The fixed carbon content of medium-sulfur calcined petroleum coke is relatively low, which may reduce its energy output and affect its effectiveness.

Potential non-uniformity: There may be certain non-uniformity in the production process of medium-sulfur calcined petroleum coke, resulting in quality fluctuations.

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

Aluminum industry: used for the supply of anode coal in the aluminum electrolysis process to provide current and heat.

Steel industry: As a metal reducing agent, it is used in steel smelting and steelmaking processes.

Chemical industry: used in the production of organic chemicals, such as the production of tempering agents, desulfurizers, etc.

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

Electrode Manufacturing: Used for casting and preparing carbon electrodes, suitable for aluminum electrolysis and other electrochemical processes.

Medium sulfur calcined petroleum coke can be used to manufacture anode coal coke, steel, organic chemicals, electrodes and other products. Its low sulfur content gives it certain advantages in environmental protection. However, its lower fixed carbon content may have an impact on energy output and performance.
