Calcined Kiln Analysis and Proximate Simulation of High-Quality Coke
A hydrogen-rich, lownitrogen-rich product gas stream is drawn from the level below the combustion zone in the kiln. High sulfur coke can be desulfurized in the process by maintaining the temperature in the calcination zone. In a vertical kiln, an elongated combustion chamber has a channel for injecting gaseous fuel into the lower center zone.

Drying: Green petroleum coke is first dried to remove any moisture content. Calcination: The dried green petroleum coke is then heated to high temperatures (typically above 1300°C) in a rotary kiln or a vertical shaft kiln. This process removes volatile compounds and moisture, converting the green coke into calcined petroleum coke, which is ...
