Commercial classifications
Petcoke Grades & Industrial Uses
Anode Grade CPC
Thermally treated lower-sulphur petcoke for carbon anode manufacturing in aluminium smelting.
Foundry & Steel Grade CPC
Recarburizer-grade material used in steelmaking and foundry operations to adjust carbon content.
Low Sulphur GPC
Uncalcined green petcoke used as feedstock for calcining facilities or specialized industrial applications.
Reference values above reproduce the commercial baseline supplied for this portal and should not be treated as a universal specification for every origin or refinery.
