Petroleum needle coke - Petroleum coke carbonizer - Calcined petroleum coke with low sulfur content
A carbon enhancing agent is a material used to increase the carbon content in metals and other materials during manufacturing processes. These agents are typically added to molten metals to improve their carbon concentration, which can enhance the properties of the final product, such as its strength, hardness, and wear resistance.
Product Description
ZSC Petroleum coke, a key ingredient in the production of Graphite Blocks, is currently widely used as a carbon enhancing agent.
Petroleum needle coke, also known as acicular coke or needle-shaped coke, offers significant advantages across various industries due to its unique characteristics and composition. Derived from the thermal cracking of petroleum feedstocks, this specialized form of coke is distinguished by its high carbon content and needle-like structure.
Petroleum coke is a byproduct obtained from refining crude oil. The residue and petroleum asphalt obtained from regular pressure distillation or vacuum distillation of crude oil can be used as raw materials for producing petroleum coke, which is then coking to obtain raw petroleum coke. The production of petroleum coke is approximately less than 5% of the crude oil used. The annual production of petroleum coke in the United States is about 30 million tons. The impurity content in raw petroleum coke is high and cannot be directly used as a carbonizing agent. It must be calcined first.
There are various types of petroleum coke, including sponge like, needle like, granular, and fluidized.
Sponge like petroleum coke is obtained by delayed coking method. Due to its high sulfur and metal content, it is usually used as a fuel during calcination and can also be used as a raw material for calcining petroleu
