Analysis of petroleum coke product quality and application

Petroleum coke is an important raw material for industries such as electrolytic aluminum, silicon metal and steel smelting, and is crucial to supporting the healthy development of related industries. The rapid development of China’s national economy and petroleum industry has stimulated the demand for petroleum coke. Petroleum coke has added a new residual oil hydrogenation project, and some of the delayed coking units are idle or the load is reduced. PetroChina and CNOOC’s petroleum coke production is relatively stable, and local refineries have increased their output and proportion due to the addition of some coking devices in recent years.

The application of petroleum coke products is closely related to product quality. Petroleum coke commonly used in the graphite electrode and anode materials industry is mainly a sulfur mass fraction of less than 0. 5% low ash premium petroleum coke; The aluminum carbon industry mainly uses medium and high sulfur sponge coke; Silicon carbide The industry mainly uses medium and low sulfur sponge coke; Most of the silicon metal industry uses high-sulfur petroleum coke; Inferior quality petroleum coke such as high as petroleum coke or projectile coke is mainly used in the fuel industry, such as cement, glass, circulating fluidized bed (CFB) boilers and other fields.Franli factory learns about the various qualities of petroleum coke, as follows:

The quality of domestic petroleum coke

In order to compare the quality of Petroleum Coke products in China, petroleum coke is divided into No. 1 coke (sulfur mass fraction ≤0.5%), No. 2 coke (sulfur mass fraction of 0.5% to 1.5%, that is, 2A, 2B and 2C), No. 3 coke (sulfur mass fraction of 1.5% ~ 3.0%, that is, 3A, 3B and 3C), No. 4 coke (sulfur mass fraction of 3.0% ~ 7.0%), No. 5 coke (sulfur mass fraction >7%).。

Imported petroleum coke quality

In order to compare the quality of imported petroleum coke, combined with customs classification data, the quality of imported petroleum coke is divided into medium and low sulfur sponge coke, high sulfur sponge coke, medium and low sulfur projectile coke and high sulfur projectile coke.

Petroleum coke quality and application prediction

China’s crude oil dependence on foreign countries is more than 65%, imported crude oil is mainly medium and high sulfur crude oil, China’s high-quality and low-sulfur petroleum coke resources are limited. The new delayed coking refineries are concentrated in coastal areas, mainly processing imported crude oil, and their products are mainly medium and high sulfur petroleum coke. The quality structure of petroleum coke in China will be gradually reduced by the proportion of low-sulfur petroleum coke, and the ratio of high-sulfur petroleum coke will further increase. The electrolytic aluminum industry will continue to be the most important application area for petroleum coke. The fuel industry is driven by “carbon peaking” and “carbon neutrality”, and the proportion of petroleum coke applications will decline. With the rapid development of the new energy vehicle and energy storage market, the demand for petroleum coke in the anode materials industry will grow rapidly. At present, the market has emerged momentum, and some anode material companies have screened ordinary petroleum coke for a wide range of ordinary petroleum coke for the production of cost-effective low-end anode materials and as graphitized insulation materials.

Domestic petroleum coke is mainly based on medium and high sulfur sponge coke, which is suitable for aluminum carbon field; From the protection of electrolytic aluminum, steel, industrial silicon and other industries. Franli factory can provide high-quality domestic petroleum coke, used in steel, industrial and other fields, if there is a related industry demand for petroleum coke can come to know the Franli Co.,Ltd.
