The classification of petroleum coke andMain Use:According to difference of sulfurcontent, can be divided into high sulfur coke (sulfur content morethan 4%), sulphur in coke sulfur content (2% 4%) and low sulfurcoke (sulfur content below 2%).
Petroleum coke products can be divided intoneedle coke, sponge coke, projectile coke and coke breeze fourkinds:
needle coke, has obviousneedle-like structure and fiber texture, mainly used forsteel-making in high power and ultra-high power graphite electrode.As a result of needle coke in sulfur content, ash content, volatilematter and true density and so on have strict quality requirements,so the production process of needle coke and raw materials havespecial requirements.
the sponge coke, highchemical reactivity, low content of impurities, mainly used in thealuminium industry and carbon industry.
Focal or spheroidal coke: theprojectile shape is round, diameter 0.6-30 mm, usually from theproduction of high sulphur, high asphaltic residual oil, can onlybe used as industrial fuel power generation, cementetc.
coke breeze: fluidized cokingprocess, the fine particles (0.1- 0.4 mm) in diameter, highvolatile, high expansion coefficient, cannot be directly used forelectrode preparation and carbon industry.
