Low sulfur and high carbon needle coke

Needle coke is commonly used to make steel in electric furnaces, to make decelerating materials for nuclear reactors, and to make ultra-high power electrodes for rocket launches. Needle coke is a high-quality variety of carbon materials vigorously developed, the appearance has obvious fibrous texture texture, color is silver gray, porous solid with metallic luster, very simple graphitization of a high quality coke, is the production of ultra-high power electrode, special carbon materials, carbon fiber and composite materials and other high-end carbon products of raw materials. According to the production of different raw materials, needle coke can be divided into oil needle coke and coal needle coke two kinds. Needle coke produced with petroleum residue as raw material is oil series needle coke. The needle coke produced from coal tar pitch and its fraction is the coal measure needle coke. The graphite electrode made of needle coke has the advantages of strong thermal shock resistance, high mechanical strength, good oxidation performance, low electrode consumption and high allowable current density. The production of needle coke can be divided into petroleum and coal measures according to the raw materials used. The petroleum system is represented by the United States and the coal measure is represented by Japan. Needle coke is a rare product both in China and abroad. Besides electrodes, it can also be applied in lithium-ion batteries, electrochemical capacitors, nuclear graphite and so on. In the international market, the price of needle coke has been rising, because there are fewer manufacturers in the country, the product is in short supply.
