Graphitized Petroleum Coke: A Superior Carbon Material from Khorshid Alyazh

Graphitized petroleum coke (GPC) is a versatile carbon material derived from petroleum coke, a byproduct of oil refining. Through a process of heat treatment and graphitization, petroleum coke is transformed into GPC, which exhibits enhanced properties such as high electrical and thermal conductivity, low thermal expansion, and excellent chemical resistance.

Production of Graphitized Petroleum Coke at Khorshid Alyazh

Khorshid Alyazh, a leading manufacturer of carbon products in Iran, has established a state-of-the-art facility dedicated to the production of high-quality GPC. The company utilizes a rigorous process that ensures consistent and reliable performance of its GPC products.

The production process involves the following key steps:

  • Selection of Petroleum Coke: Khorshid Alyazh carefully selects high-grade petroleum coke as the starting material, ensuring optimal properties for graphitization.
  • Heat Treatment: The selected petroleum coke is subjected to controlled heating in a furnace under an inert atmosphere. This step initiates the graphitization process and promotes the alignment of carbon atoms.
  • Graphitization: The heat-treated coke is further processed through a temperature-controlled graphitization furnace, typically above 2,500°C (4,532°F). During this stage, the carbon atoms rearrange into a highly ordered graphite structure, resulting in improved electrical and thermal conductivity.
  • Quality Control: Throughout the production process, Khorshid Alyazh employs stringent quality control measures to ensure the consistent performance of its GPC products.
