Columnar Graphite Carburizer Recarburizer Suitable for Casting Industry
Petroleum coke is a product produced after crude oil is distilled to separate light and heavy oil, and then the heavy oil is transformed through a thermal cracking process. From the appearance, the coke is a black block (or particle) with irregular shape and different sizes and granular, it has a metallic luster, and the coke particles have a porous structure. Petroleum coke is a black or dark gray hard solid petroleum product that is porous. It is a carbon body composed of granular, columnar, or needle-shaped crystals of tiny graphite. Petroleum coke is composed of hydrocarbons. The main element is carbon, with a carbon content of 90-97% and hydrogen 1.5-8%. It also contains nitrogen, chlorine, sulfur and heavy metals. Petroleum coke is cheap and has high carbon content.
Introduction to calcined petroleum coke CPC and graphitized petroleum coke GPC:
Calcined coke is mainly used to produce graphite electrodes, carbon paste products, diamond sand, food-grade phosphorus industry, metallurgical industry, calcium carbide, etc. Among them, graphite electrodes are the most widely used. Petroleum coke calcination is a primary processing of raw materials and is a necessary process for producing graphite electrodes.
Graphitized petroleum coke is to convert petroleum coke into a hexagonal layered crystalline carbon crystal at a high temperature of about 3000 degrees in a graphitization furnace, that is, petroleum coke becomes graphite. This process is called graphitization. Petroleum coke processed through the graphitization process is called graphitized petroleum coke.
Petroleum coke is composed of hydrocarbons. The main element is carbon, with a carbon content of 90-97% and hydrogen 1.5-8%. It also contains nitrogen, chlorine, sulfur and heavy metals.
