Carbon Raiser

Carbon Raiser
Calcined Petroleum Coke (CPC) is obtained by calcining Raw Petroleum Coke (RPC) at temperatures as high as 1400’C. RPC is a by-product of the oil refining process and is derived from the distillation of petroleum crude in delayed cokers. CPC is used in the Aluminum, Graphite Electrode, Steel, Titanium Dioxide and other carbon consuming industries. Calcined Petroleum Coke is also known as Recarburiser / Laddle additive / Carbon raiser.


Raw Petroleum Coke received from the refinery is fed into a rotary kiln. The coke gradually moves towards the lower end of the kiln and during its movement down the kiln all moisture and volatile matters present in the RPC are driven off. It is a self sustaining process with the burning of hydrocarbons present in the RPC providing for the heat required for calcination. The product received at the end of the process is a highly electrically conductive carbon called Calcined Petroleum Coke.
