Calcined petroleum coke is a key ingredient in the production of aluminum. It is made by placing high-quality green “green” petroleum coke in a rotary kiln, where it is heated to temperatures between 1200 and 1350 ˚C (2192 and 2460 ˚F). The high temperature removes excess water, extracts any remaining hydrocarbons and changes the coke’s crystal structure, resulting in a denser, more conductive product. In a matter of hours, calculated petroleum coke cools from 1350 ˚C to below 0 ˚C, at which point it can be safely handled and transported to storage silos or placed directly into containers, trucks, railcars, barges or ships.
Calcined petroleum coke has a sponge-like structure and plays an important role in the manufacture of anodes. The pores allow the bonded material to penetrate the coke particles and form solid carbon blocks through which aluminum smelters conduct electricity to their ports. By the time the anodes are consumed, aluminum is produced at a rate of approximately 40 tons per 100 tons of petroleum coke. Currently, there are no known commercially viable alternatives to petroleum coke in the manufacture and utilization of aluminum anode smelting.
Most of Yunai’s calcined petroleum coke is used in the primary aluminum industry, while another is used in the steel industry as a recarburizer. Other uses include the production of titanium dioxide, which is used as a pigment in paints, plastics, sunscreens and food coloring.
