PETROLEUM TOTAL AND CALCINED COKE

Petroleum cokes are carbonaceous materials - the carbon content in them is 92-95% (wt.). Depending on the quality of the raw materials, they may contain 2-7% hydrogen, 1-7% (wt.) sulfur, nitrogen, and oxygen. In coke, there are also other and non-metals, such as vanadium, iron, nickel, sodium and others that make up its inorganic part and increase the ash content of coke, which is undesirable.

The demand for petroleum coke is very significant. The main consumer of coke is the aluminum industry: coke serves as a reducing agent (anode mass) when smelting aluminum from aluminum ores (bauxite). The specific consumption of coke is quite high - 550-600 kg / t of aluminum.

Other applications of coke:
• as a raw material for the manufacture of electrodes used in steelmaking furnaces;
• for the production of carbides (calcium, silicon), which are used in the production of acetylene;
• in the production of grinding materials in the manufacture of conductors, refractories, etc.
