[0002] Carbon product is a kind of non-metallic material mainly composed of carbon element, with good high-temperature resistance, thermal shock resistance, high conductivity and other characteristics, widely used in metallurgy and other fields.Petroleum coke and pitch coke and other materials usually need to be desulfurized before being used as carbon product raw material, to reduce its sulfur content, improve the performance of final product and reduce environmental pollution.

[0003] At present, common high-temperature calcination process is used to remove sulfur from raw materials, which principle is to promote organic sulfur and inorganic sulfur in raw materials to convert into sulfur dioxide (SO) gas release under high temperature environment.Although this process is equipped with tail gas treatment equipment to intercept and dispose of emitted sulfur dioxide, to reduce the impact on the ecology, the specific method is usually to mix limestone slurry with flue gas, to promote it to react with sulfur dioxide to form calcium sulfite, and then further oxidize to form calcium sulfate (i.e., gypsum).However, when dealing with high-concentration flue gas, only relying on the way of spraying lime slurry exposes limitations: uneven contact of flue gas with lime slurry may cause sulfur dioxide not to fully participate in the reaction, so that desulfurization is not complete, and the gas discharged still carries a small amount of sulfide residue, which threatens air quality.
