Needle coke is an important chemical raw material, which is widely used in many fields because of its unique physical and chemical properties. In the upstream and downstream related products of needle coke, there are mainly the following aspects:

1. Upstream product

The production of needle coke is mainly made of petroleum coke, coal tar, etc., through high temperature cracking, carbonization, graphitization and other processes. Therefore, the upstream products of needle coke mainly include petroleum coke, coal tar and other carbon raw materials.

2. Downstream product

needle coke, as a high-quality carbon material, is widely used in many fields, so its downstream products are also very rich. The following are the main downstream products of needle coke:

(1) Electrode material: Needle coke has the characteristics of high conductivity, high thermal stability, low resistance, etc., so it is widely used in the manufacture of electrode materials, such as lithium-ion battery anode materials, Supercapacitor electrode materials, etc.

(2) Carbon fiber: Needle coke can be used as a raw material for the manufacture of carbon fiber. Carbon fiber has the advantages of high strength, high modulus and low density, and is widely used in aerospace, automobiles, sports equipment and other fields.

(3) carburant: needle coke can be used as carburant added to the molten iron, molten steel, improve the carbon content of molten steel, improve the performance of steel.

(4) Metallurgical accessories: Needle coke can also be used as metallurgical accessories for the manufacture of refractory materials, insulation materials, etc.

In short, needle coke as an important chemical production raw materials, its upstream and downstream related products are very extensive, involving many fields, such as new energy, new materials, metallurgy and so on.
