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. A narrow particle size range for this test minimizes the possibility for variation due
2017/2/12· Aluminium smelters are tightening bulk density specifiions for Calcined Petroleum Coke while refiners are sacing green coke densities at the cost of outputs. Previously, Apparent Density using mercury was popular for defining CPC density. But after AD testing was discontinued owing to environmental issues arising out of mercury usage, each

Calcined Petroleum Coke (CPC) is a form of highly electrically conductive, dense Carbon with very low specific Electrical Resistance, and having fixed Carbon of approximately 99.5%. CPC is used extensively as Anode in Alumina Smelters, and in the manufacturing of Graphite/ Graphite Electrodes, and Thermal Paste for Ferro Alloys & industries in Arc Furnaces.
2019/7/23· In terms of calcination quality, the true density, specific resistance, compacted packing density, air reactivity and CO2 reactivity of the calcined coke are closely related to anode consumption. The volatile matter has natural advantages over the rotary kiln.
2020/8/7· The annual production capacity of graphite electrode, electrode paste, calcined petroleum coke and semi coke reaches 80,000 tons, 200,000 tons and 250,000 tons, 1000,000tons respectively.

some calcined coke quality parameters. The most universally reported difference is the higher bulk and apparent density achieved with a shaft calciner. This is due to the slower heat up rate of green coke. The loss of VM creates porosity in coke. Lower VM
2016/4/1· Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons, and modify the crystalline structure of the coke into a denser,

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
Section 95113(l)(2) of MRR requires the annual mass of calcined coke produced on-site during the data year to be reported in metric tons (not short tons, which is the case for most solid products). Calcined coke production is covered product data, but petroleum
