Properties of calcined petroleum coke

Petroleum coke is a by-product of the pyrolysis of feedstock oil in delayed coking units at high temperatures to produce light oil products. The output of petroleum coke is about 25-30% of the raw oil. Its low calorific value is about 1.5-2 times that of coal, the ash content is not more than 0.5%, the volatile matter is about 11%, and the quality is close to anthracite.
