Carburizer

Petroleum coke carburizing agent is a black or dark gray hard solid petroleum product with metallic luster and porous. It is a kind of carbon body composed of granular, columnar or acicular graphite crystals. Petroleum coke is composed of hydrocarbons, containing 90-97% of carbon and 1.5-8% of hydrogen. It also contains nitrogen, chlorine, sulfur and heavy metals. Carburizing agent for calcined coke

The production of raw petroleum coke is less than 5% of the crude oil used. The annual output of crude petroleum coke in the United States is about 30 million tons. Because of the high content of impurities in raw petroleum coke, it can not be used as carburizer directly, but must be calcined first.
