Application
Depending on its quality, petroleum coke can be used in industries such as graphite, smelting and chemical industry, etc
Petroleum coke, as a byproduct of petroleum, is produced in the process of petroleum processing, that is, the crude oil is distilled to separate light and heavy oil, and the heavy oil is converted into petroleum coke by hot cracking. If petroleum coke can be obtained directly from petroleum processing, then the petroleum coke is raw coke or ordinary coke. Petroleum coke has irregular shape, dark gray or black, porous structure and metallic luster.

Petroleum coke is after distillation according to quality, and the oil separation of crude oil, heavy oil by cracking process, transformed into products, look from the exterior, coke for the irregular shape, size of the black block (or particles), with a metallic luster, coke particles with porous structure, the main elements for carbon, occupies more than 80%, hydrogen-containing 1.5% – 8%, The rest are oxygen, nitrogen, sulfur, and metal elements.
Petroleum coke belongs to a class of graphitized carbon, the microcrystalline petroleum coke, and metallurgical coke, carbon mesh sheet between the overlap is relatively neat, the distance between the sheet is small; At the high temperature of graphitization, the average grain thickness (Lc) and average grain width (La) of carbon grid sheets increase, and the lamellar spacing (D) decrease. The lattice constants (A0 and C0) are close to natural graphite, and the resistivity decreases significantly while the true density increases correspondingly. So using petroleum coke as raw material can produce graphite electrodes with low resistivity.
Petroleum coke can be divided into low sulfur, medium sulfur, and high sulfur petroleum coke according to its sulfur component. Petroleum coke with different sulfur content can be used in different industries, such as petroleum coke can be used in graphite, smelting, and chemical industry according to its quality.
Low sulfur, high-quality coke such as needle coke, is mainly used for manufacturing ultra-high power graphite electrodes and some special carbon products; Needle coke is an important material for developing new technology of electric furnace steelmaking in the steelmaking industry.
Medium sulfur, common coke, large number of aluminum smelting.
High sulfur, common coke, is used in chemical production, such as manufacturing calcium carbide, silicon carbide, etc., but also as a metal casting fuel.
Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used in aluminum smelting and graphite manufacturing. The other is mainly used for carbon products, such as graphite electrodes, anode arc, provide steel, non-ferrous metals, aluminum smelting; Carbonized silicon products, such as various grinding wheels, sand, sandpaper, etc.; Commercial calcium carbide for the production of synthetic fiber, acetylene, and other products; Can also be used as fuel, but do fuel needs to use a graded impact mill for ultrafine grinding, through JZC-1250 equipment made of coke powder can be burned, with coke powder as fuel is mainly some glass factory, coal water slurry plant.
The petroleum coke produced by Franli belongs to the low sulfur petroleum coke, which is one of the main raw materials for graphite and anode materials. Franli’s petroleum coke is of low price and good quality and has been widely praised by customers. Franli will also work harder and produce more and better products.
