Calcined Petroleum Coke (CPC) is the product from calcining raw petroleum coke (RPC). The raw coke is the product of the Coker unit in a crude oil refinery. CPC is used to make anodes for aluminium smelting and is also used in dioxide industry, steel and titanium.
Abstract. Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.
In the calcination of petroleum coke in a rotary kiln, procedure wherein air is controllably supplied internally of the kiln to burn the removed volatiles, as by selection or adjustment of the amount of such air and of the speed of coke travel down the kiln, so that all or nearly all of the heat for calcining the coke is provided by such combustion, and so that a suitably high temperature is ...
Yield is calcined coke. During calcination there is a complete removal of moisture and volatile matter, seeming and real density increases, electrical conductivity and mechanical density increases . Coke calcining is carried out in the drum rotating furnace with length 59,5 m long, diameter 3,6m.,established at an angle of 4,17 0.
Coke Calcining Plants. Coke-calcining plants receive green petroleum coke from oil refineries. The green coke is blended and fed into rotary kilns operating up to 2800°F under a reducing condition. The material exits the rotary kiln as calcined coke with a correct crystalline structure and electrical conductivity properties.
evaluated. Although density of the calcined coke decreases when calcining at high temperatures, the objective of this work is to determine if high sulfur (low cost) raw coke can be calcined and desulfurized for use as calcined low sulfur industrial product (IP) grade coke. Density and metals are usually not a problem for IP coke.
2014. 2015. 2016. 1998. Rain Calcining Limited begins operations in Visakhapatnam, India, with a production capacity of 0.3 million tons of calcined petroleum coke per annum. 2005. Rain Calcining Limited doubles production capacity of calcined petroleum coke to become the fifth largest global producer of calcined petroleum coke. 2007.
Then, the coke heated to a temperature of about 800° to 980° C. in the burning kiln 3 is introduced into the final calcining kiln 4 through a coke feeding device 13, where the coke is heated to a calcining temperature of 1,200° to 1,500° C. and thus calcined.

Vibrated bulk density (VBD) is a quantitative measurement used in the aluminum industry to evaluate the density of calcined petroleum coke. In the calcining industry, the reproducibility of the current ASTM International (ASTM) method D4292 generates a wide range of VBD data. Therefore, Oxbow Calcining investigated the VBD procedure – D4292.
Calcined petroleum coke is used for the production of carbon anodes in the Hall-Héroult aluminum smelting process due to a combination of low impurity levels, ready availability, and relatively low cost.
