Petroleum coke is a solid porous product obtained by coking petroleum raw materials. Its color is often varied from dark gray to black. It is used for the electrodes and corrosion-resistant equipment manufacturing or as reducing agent upon receipt of ferroalloys, etc.
The elemental composition of raw or unheated petroleum coke (%) is: 91-99.5 C, 0.035-4 N, 0.5-8 S, 1.3-3.8 (N + O), the rest of it are metals.
The main indicators of quality are the content of S, ash, moisture (usually not more than 3% by weight), the yield of volatile substances, particle size distribution, mechanical strength.
according to the S content, low-sulfur (up to 1%), sulfur (up to 2%), high-sulfur (more than 2%);
according to the ash content on low-ash (up to 0.5%), medium-ash (0.5-0.8%), high-ash (more than 0.8%);
according to the granular composition into a lump (fraction with a particle size of more than 25 mm), "nut" (6 25 mm), fines (less than 6 mm).
