How to make petroleum coke?


Petroleum coke for carburizing agent is often used in the production of metallurgical cast iron, petroleum coke is crude oil distillation will be heavy and light oil separation, heavy oil by the process of hot cracking, transformed into products, from the appearance, coke for irregular shape, different size of black block (or particles), metallic luster.

The morphology of petroleum coke varies with the process, operating conditions and feeding properties.From the production of petroleum coke site are known as coke (green cokes), containing some carbonized volatile hydrocarbon compounds, coke can be used as fuel grade petroleum coke, if you want to do aluminum anode or steel electrode, it needs to be calcined again by high temperature, so that it is completed carbonization, reduce volatile to the minimum degree.The coke produced in most oil coking facilities is a black brown porous solid, irregular lump, which is also known as sponge coke.The second type of petroleum coke with better quality is called needle coke, which is more suitable for electrodes because of its lower resistance and thermal expansion coefficient.The third hard petroleum coke is shot coke, which is pellet shaped and has a small surface area that makes it difficult to coke, so it is not used for much.

The above is the preparation method of petroleum coke, you can do a simple understanding, if you need petroleum coke, please contact us, our production of petroleum coke specifications complete, price stability, large quantity of preferential, welcome to buy!
