Calcined petroleum coke has been used for the production of carbon anodes in the Hall-Héroult aluminum smelting process for over 120 years. Prebaked anodes are produced with 55–65% CPC, 13–15% coal tar pitch
Using the most advanced production and testing equipments, with an annual production capacity of 100000 tons of calcined petroleum coke. our company for the domestic northeast area only one through the international authoritative certifiion body (ISO9001

LC50 (Green petroleum coke) > ~ 0.058 mg/L LC50 (Calcined petroleum coke) > ~ 0.045 mg/L Repeated-Dose Toxicity Green petroleum coke (CASRN 64741-79-3) (1) Sprague-Dawley rats (150//group) were administered (Delayed process) green petroleum coke
Coke used in anodes is usually petroleum coke which is a by product of oil refineries. It is of limited interest to the producers as it constitutes only about 2%

and the high percentage of fines produced. Calorific value The calorific value (CV) or Heat of coustion is a measure of the heat liberated as a result of the complete coustion of the fuel. Customarily, the basic calorific value for petroleum coke and other solid
calcined coke and recycled butt fractions. The total variation was about ±5%. For each group of tests, only the percentage of a chosen fraction group was changed gradually (1% at a time). iv) Finally, an anode recipe with a suitable maximum particle size and
During the anode fabriion, calcined petroleum coke, recycled material (butts, green and baked rejects), which is also called dry aggregate, and coal tar pitch are blended in certain percentages and mixed in kneader. The composition of this mixture is known
The incoming petroleum coke (C) is screened at (S) into two size fraction F1and F2. The coarse fraction Fl having an average particle size distribution of 0.371 inches to +4 mesh is produced. The intermediate size fraction F2having an average particle size distribution of −4 to +14 mesh is also produced.

heat treatment of homogeneous raw material mixture consisting of 99.5% CPC and 0.5 wt %, boron powder in the EAAPR by the appliion of hybrid nitrogen cum argon arc plasma for 45 minutes showed real density of 2.15 g/cc, electrical resistivity of 0.022
Petroleum coke (both green and calcined) is a black-colored solid produced by the high pressure thermal decomposition of heavy (high boiling) petroleum process streams and residues.
coke particles used for making the anode paste. The pitch/coke ratio was 16.2/100 for all samples. Pitch and different size fractions of coke were individually weighed and added into the mixer to avoid variations in the composition of samples. Coke fractions and
In LTOC, the percentage of Li 2TiO 3 is 35.6 wt% (ESI, Section 2†). The EDS analysis indies that the LTOC contains Al, Si, and S impurities, but not contains nitrogen (ESI, Section 3†). The XRD analysis shows that the coke has only a broad 2TiO
Mixing temperature is usually chosen 60-70°C above the R&B softening point and mixing time of about 30 minutes. In case of paste for soderberg electrode, the paste is cast into blocks and sent to the customers, who break into small lumps (150 mm to 200 mm) and preheat them before charging into electrodes.
It has also been observed that cross-linkage in anthracite coal is more than in petroleum coke; as a result both RPC (fixed carbon 87–95%, VM = 5–15%, and H = 4% approx, moisture = 0.5–2%) and CPC (calcined at 1300 C and containing 97–99% fixed = 0.3
Further heating of green coke to remove the volatiles produces coke (petroleum), calcined, hereinafter referred to as calcined coke. The carbon content for green and calcined coke ranges from 84-97% (CONCAWE 1993).
Electrominerals India''s primary business is the manufacture and supply of high-quality Calcined Petroleum Coke (CPC) which is the purest form of Carbon, containing over 99.5% of it. Along with the Calcined Coke, the Company also specializes in the production of Electrode Carbon Paste (ECP) and Tamping Paste used widely in the Ferro Alloys and industries and also in the production of …
