Coke must be used as fuel because it builds a carrier framework for the material and the hot melt flow. Figure 1-1 shows schematically a shaft kiln as an example for the calcination of limestone. Limestone particles are filled in a container, weighed on a balance, lifted to the top of the kiln and then poured into the shaft.

Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. While CPC can be created using a number of processes -- including rotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways: Drying.

Typical temperatures for a rotary coke calcining kiln are between 2200°F (1200°C) and 2400°F (1315°C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures. Petroleum coke calcining operators prefer single-layer brick linings using rotary kiln block (RKB's).
