Calcined petroleum coke

Calcined petroleum coke is a product obtained from the high temperature treatment of specified feed-stocks. The feed-stocks (raw petroleum coke) are derived from the distillation of petroleum crude in delayed cokers. Raw petroleum coke is a hard brittle substance, shiny and oily in appearance, very rich in fixed carbon with a very low ash content.

Raw petroleum coke is calcined before it can be usefully employed for various applications in industries as diverse as graphite to metallurge. Calcination consists of heating raw petroleum coke to rid it of volatiles causing it to shrink to obtain dense and strong particles.

Graphite India produces high quality calcined petroleum coke in two basic grades. High Density (HD) and Normal Density (ND). The properties of these grades are tabulated below.
