The available anode-quality petroleum coke is not sufficient to cover the need created by the increase in the world aluminum production. Understanding the consequences of varying calcined coke quality is necessary to possibly compensate for the reduction in coke quality and adjust the anode paste recipe in the subsequent use of coke in order to obtain economically viable production of aluminum.

Coke anodes are made of Calcined Petroleum Coke, recycled anode butts, and coal-tar pitch (binder).The anodes are manufactured by mixing aggregates with coal tar pitch to form a paste with a doughy consistency. This material is most often vibro-compacted but in some plants pressed.

Green petroleum coke is generated by delayed coking during the conversion of crude oil into liquid fuels such as gasoline and jet fuels. Green coke quality is derived mainly from the quality of crude oil that a refinery consumes.The calcined petroleum coke is used to make anodes for the aluminium, steel and titanium smelting industry.
Carbon anodes are an essential part of the primary aluminum production. They are made of coal tar pitch, calcined petroleum coke, recycled anodes and butts. As pitch acts as a binder for the anode, its proper distribution in a green anode has a great impact on the properties of the baked anode. Information on cracks in anodes is important for the quality of the baked anode.
This of course, excludes the carbon in the anodes, which are made with coal tar pitch and petroleum coke. From the equation above, and the atomic weight of aluminum, 28.96 grams per mole, and the molecular weight of carbon dioxide, 44.095 grams per mole, and the ratio

5.1 The grain stability of calcined petroleum coke determines the resistance to breakdown of +4 mm particles used in the manufacture of carbon anodes for use in the reduction process of aluminum. 5.2 Calcined petroleum cokes have to be relatively easy to grind for fines production but strong enough to withstand forming pressures and thermal stresses occurring when the anodes are used in the
5.1 Vibrated bulk density, VBD, is an indior of calcined petroleum coke porosity, which affects its suitability for use in pitch-bonded carbon appliions. (Warning— Vibrated bulk density for a sample of calcined petroleum coke is strongly dependent upon average particle size and particle size range.Bulk density tends to increase with decreasing coke size.
Anodes used in aluminum production are made of dry aggregate (calcined petroleum coke, baked and green rejects, and butts) and coal tar pitch. Dry aggregate, prepared using a predetermined granulometry, is mixed with pitch. The resulting anode paste is compacted either in a press or vibrocompactor to produce green anodes.

The information on the interactions between coke and pitch is of great value for the aluminum industry. This information can help choose the suitable coke and pitch pairs as well as the appropriate mixing parameters to be used during the production of anodes.
04.11.1997· The manufacture of the prebaked carbon anodes generally proceeds by mixing crushed, calcined delayed petroleum coke, or in some instances, calcined fluid petroleum coke or calcined pitch coke, with remnants of earlier manufactured prebaked anodes and a binder, such as coal tar pitch, followed by shaping the green mixture into blocks and baking of the blocks to about 1150° C.

Converting tar-sands oil into usable fuels requires a huge amount of energy, and much of the black gunk that’s refined out of the crude in this process ends up as petroleum coke. Petcoke is like concentrated coal – denser and dirtier than anything that comes out of a mine.
