Common uses and classifications of petroleum coke
What is petroleum coke?
Petroleum coke is a product of crude oil that is distilled to separate light and heavy oils, and the heavy oils are then thermally cracked. From the appearance, the coke is black lumps (or particles) with irregular shapes and different sizes. ), with a metallic luster, the coke particles have a porous structure, the main element is carbon, which occupies more than 80%, contains 1.5%-8% hydrogen, and the rest are oxygen, nitrogen, sulfur, and metal elements.
Petroleum coke belongs to the category of easily graphitized carbon, which has unique physical, chemical, and mechanical properties. The non-volatile carbon, volatile matter, and mineral impurities (sulfur, metal compounds, water, ash, etc.) in the heating part determine the coke Chemical nature.
Petroleum coke classified according to the heat treatment temperature
Petroleum coke classified by heat treatment can be divided into petroleum coke before calcining (green coke) and petroleum coke after calcining (calcined coke).
Specializes in sieving calcined petroleum coke of various sizes, namely 1-3mm, 1-5mm, 1-10mm, 1-20mm, etc.
Can be customized according to needs, screening various types of sponge calcined coke;
It mainly produces low-sulfur calcined petroleum coke and medium-sulfur calcined petroleum coke and is in a leading position.
The monthly supply is about 5,000 tons, the inventory is large, and the delivery is fast.
Uses of petroleum coke
Depending on its quality, petroleum coke can be used for graphite production, smelting, and chemical industries.
Low-sulfur, high-quality cooked coke, such as needle coke, is mainly used to make ultra-high power graphite electrodes and some special carbon products. In the steelmaking industry, needle coke is an important material for the development of new electric furnace steelmaking technology.
Medium-sulfur, ordinary cooked coke is used in aluminum smelting in large quantities.
High-sulfur, ordinary green coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., and also as a fuel for metal casting.
