The vacuum residue of petroleum is cracked by coking at 500 ～ 550 ℃ to produce black solid coke. Its appearance is a black or dark gray honeycomb structure, and the pores in the coke block are mostly oval and interpenetrating. It is generally considered to be an amorphous carbon body; or a highly aromatized polymer carbide that contains fine graphite crystals in a needle-like or granular structure. The carbon-hydrogen ratio is high, ranging from 18 to 24. Relative density is 0.9 ～ 1.1, ash content is 0.1% ～ 1.2%, volatile matter is 3% ～ 16%.
The limestone is fed into the bucket elevator and subsequently transported to the raw material warehouse for grinding.
After grinding, the finished products are gathered by powder concentrator, and then conveyed to a screw conveyor.
The finished products are transported to the storage warehouse, while the excess gas is filtered by the dust collector.
The whole system is equipped with three pulse dust collectors to guarantee that the whole system is free of dust leakage.
The system is outfitted with an intelligent PLC control cabinet and an upper computer.

Low sulfur coke can be used as anode paste and pre-baked anode for aluminum plant and graphite electrode for steel plant. Among them, high-quality low-sulfur coke (sulfur content less than 0.5%) can be used to produce graphite electrodes and carbon enhancers. General quality low sulfur coke (sulfur content less than 1.5%) is often used to produce prebaked anodes. The low-quality (low-sulfur) petroleum coke is mainly used for smelting industrial silicon and producing anode paste.
