High-volatile petroleum coke is prone to “cracking” or “slagging” during calcination
Mechanism Analysis: Explosion (Bursting) Phenomenon: Rapid escape of volatile matter: When the volatile content in petroleum coke is high, as the temperature rises during the initial stage of calcination, the volatile matter escapes rapidly. If the escape rate is too fast, significant steam pres...Read more -
Does the moisture in the raw coke need to be forcibly dried before calcination?
Generally, it is necessary to forcibly dry the moisture in raw coke before calcination, especially in the following scenarios where drying is an essential process: I. Negative Impacts of Moisture on the Calcination Process 1. Affecting the Efficiency of Volatile Matter Discharge When raw coke (su...Read more -
What influence does the microstructure of petroleum coke (needle-like, spongy, and pellet-like) have on the calcination shrinkage rate and true density?
1. Needle Coke: A Typical Example of Low Shrinkage and High True Density Structural Characteristics: Needle coke exhibits a fibrous or elongated structure with elongated elliptical pores arranged in an ordered manner. This structure demonstrates excellent densification capability during c...Read more -
What is the core difference in calcination behavior between oil-based coke and coal-based coke?
The core differences in the calcination behavior between oil-based coke and coal-based coke lie in the distinct reaction pathways driven by differences in their raw material chemical compositions, which subsequently lead to significant variations in crystal structure evolution, physical property ...Read more -
