Calcination principle of calcined Petroleum Coke

Calcined petroleum coke has a wide range of uses, mainly used in pre-baked anode and anode paste used in electrolytic aluminum, carbon industry to produce carbonization agent, graphite electrode, smelting industrial silicon and fuel and so on. 

So what is the principle of calcination? 

Let's take a look at this: 

Calcination principle of calcined petroleum coke: 

The process of heat treatment of carbon calcination at high temperature (1200 ℃-1500 ℃) under the condition of isolating air is called calcination. 

Calcination is a pretreatment process for carbon production. 

A series of significant changes have taken place in the composition and microstructure of all kinds of carbon raw materials during calcination. 

Calcined petroleum coke, anthracite and delayed asphalt coke all contain a certain amount of volatile matter, which needs to be calcined. 

The coking temperature of asphalt coke produced by metallurgical coke and coke oven is relatively high (above 1000 ℃), which is equivalent to the calcination temperature of carbon plant. 

Natural graphite can also be calcined in order to improve its lubricity. 

Generally speaking, the calcined material is hard, brittle, easy to crush, grinding and screening.
