Graphite Petroleum Coke

Graphite Petroleum Coke Manufacturer

Graphite petroleum coke has many advantages, making it favored in many industrial fields.

High electrical conductivity

It has high electrical conductivity, can conduct current effectively, and performs well in some application scenarios that require good electrical conductivity.

Good thermal stability

It also has good thermal stability, can maintain the relative stability of the structure in the high temperature environment, is not easy to deformation or decomposition, can withstand a large temperature range, from normal temperature to higher temperature range can be used normally.

Chemical stability

The chemical stability of graphite petroleum coke is also relatively excellent, which can resist the erosion of a variety of chemical substances, and can still exist stably in some corrosive media environments.

Good density

In addition, its density is relatively moderate, which ensures a certain quality and strength, without being too heavy, and is convenient for processing and application in different industrial equipment and processes.

Specifications of graphite petroleum coke

For each graphite petroleum coke product, we will provide a detailed quality inspection report, including its ash content, volatile content, resistivity and other key performance indicators, so that users can choose according to their own needs.

Production process

The production of graphite petroleum coke is a complex and delicate process that involves several key steps:

Step 1: raw material pretreatment

First of all, the raw materials of petroleum coke should be screened and pretreated to remove impurities and large particle inhomogeneity. This step is essential to ensure the quality stability of subsequent products. Usually a combination of mechanical screening and physical cleaning is used to separate the impurities that do not meet the requirements, so that the raw material can reach a certain purity and particle size standards.

Step 2: high temperature calcination

The pre-treated petroleum coke raw material is sent to the high-temperature calcining furnace for calcining. The calcination temperature is generally between 1200°C and 1500°C, and in this process, a large amount of volatile matter in petroleum coke is removed, while its structure changes and gradually changes to the graphitized structure. High temperature calcination can further increase the density and strength of petroleum coke, improve its electrical conductivity and thermal stability.

Step 3: graphitization

The calcined petroleum coke also needs to be graphitized. This step is carried out in a graphitization furnace at a higher temperature, which can reach 2500°C – 3000°C. In such a high temperature environment, the carbon-carbon bonds in petroleum coke are further rearranged and optimized to form a more structured graphite crystal structure, which significantly improves its graphitization degree, thereby significantly improving its key properties such as electrical conductivity and thermal stability, so that it can meet the stringent requirements of high-end industrial applications.
