Oil & Gas: Petroleum Coke (PETCOKE) : Global Oil and …
Compared to needle coke, honeyco coke has a lower coefficient of thermal expansion and a lower electrical conductivity. Fuel-grade coke is classified as either sponge coke or shot coke morphology. While oil refiners have been producing coke for over 100 years, the mechanisms that cause sponge coke or shot coke to form are not well understood and cannot be accurately predicted.
