Production Process and Development Market of Calcined Petroleum Coke

Forging is the first process of petroleum coke heat treatment. In general, the high temperature heat treatment temperature is about 1,300℃. It aims to remove impurities such as water, volatiles, sulfur and hydrogen in petroleum coke, and to realize the changing structure and physicochemical properties of various carbon materials. This method can reduce the hydrogen content of petroleum coke regeneration products and improve the degree of graphitization, thus improving its mechanical strength, density, electrical conductivity and oxidation resistance.

At present, the petroleum coke forging in China mainly adopts rotary kiln forging, tank forging furnace, rotary furnace and electric thermal forging furnace. Due to the different structure of some furnace types, the process is also very different. Domestic and foreign electrolytic aluminum supporting prebaked anode and commercial prebaked anode production enterprises of petroleum coke most using tank type forging furnace, rotary kiln forging, including tank type forging furnace heating method is with refractory brick heat for indirect heating, and rotary kiln heating method is with combustion gas direct contact material heating.

Process of the calcined petroleum coke

Whether graphite cathode carbon block used in the production of forging petroleum coke, or pre-baked anode carbon block production used after forging petroleum coke, although they have different requirements for raw materials, but their production process is the same, namely without any other raw materials, through forging forging coke, can effectively improve the physical properties of coke, such as electrical conductivity, density, etc.

After calcination, petroleum coke is commonly used in two production processes, rotary kiln production process and tank furnace production process. Most foreign petrochemical enterprises use the rotary kiln production process to forge petroleum coke, while the domestic mostly pot furnace production process to forge petroleum coke.

Its production process is relatively simple, mainly to control the forging time and forging temperature, can process various kinds of petroleum coke, but can not process high volatile combustion. A can stove can be made.?

Develop the market??

A growing number of companies have been committed to developing more optimized tank furnace production processes, including increased capacity to improve automation, improve waste heat and waste gas treatment. Therefore, the production process of the tank furnace will be the main direction of the future furnace development.

In foreign countries, the forging process of petroleum coke is completed in an oil refinery, and the petroleum coke is forged directly into the forging device. Chinese refineries have no forging device, so the price of petroleum coke produced is low. At present, China's oil coke and coal forging are mainly concentrated in the metallurgical industry, such as carbide plant, aluminum plant, etc.

Forging oil coke has a good sales market in China, and its main users are aluminum. In foreign markets, the outlook for fake oil coke is also optimistic, mainly for exports to the United States, Japan, Singapore and Russia. The price of general oil coke and forging coke is hundreds of yuan per ton. Refining and coking is an important means to improve the economic benefit of refinery coking plant. Post-treatment can increase the petroleum coke content?significantly.?
