Petroleum coke is the main raw material for aluminum electrolysis anodes. Quality of coke determinates the technology, ecology and economics of production of aluminum. From the aluminum producers point of view, petroleum coke should have the following characteristics: - a minimum ash content and the absence of impurities, - high resistance to oxygen and CO2, - low porosity and electrical resistivity - mechanical strength, acceptable for processing - good microstructure. Petroleum coke is produced from petroleum residues and secondary petroleum products. Because of the peculiarity of the technology, the quality of petroleum coke is a compromise between the receipt of light fuel and raw coking. It is not surprising that only a very small amount of coke can satisfy all the requirements of the aluminum industry. The purpose this article is formation of cokes properties from the beginning of oil refining up to the anode plant. The article is the first in a lot of cooperated works of the Siberian Federal University and specialists of the Achinsk refinery, dedicated to construction and development of production of petroleum coke at the Achinsk refinery.
