REDUCTION OF PUFFING BY NITROGEN COMPOUNDS IN COAL-BASED NEEDLE COKE PRECURSORS FOR ELECTRODE GRAPHITE Peter G. Stansberry and C. F. Chang GrafTech International Holdings, 12900 Snow Road, Parma, Ohio 44130-1077
1/2/2015· For the manufacturing of graphite electrodes, the petroleum coke (80% wt.) is of premium quality, called needle coke, and the binder pitch of about 20% wt. The green mix follows the compression moulding process in which green electrodes are formed, depending on the intended appliion.
No 3,112,181 to Peterson et aldescribes the production of isotropic coke using petroleum distillates. Contaminants such as boron, vanadium, and sulfur have prohibited the use of some materials as the source of isotropic coke suitable for use in nuclear reactors Less than about 1.6weight percent sulfur is preferred to avoid puffing problems upon graphitization and fabriion of the coke.
petroleum coke under a temperature of 2, 500-3, 500 C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc.It can be used as carbon raiser (Recarbonizer) to produce high quality steel, cast iron and alloy.It can also be used in plastic and rubber as an additive.
Using high-quality petroleum coke as raw material,our company produces graphitized petroleum coke in high temperature of 2600 by graphitizing craft. Graphitized petroleum coke has the features as following:low ash ,low sulphur,low resistivity. The product can

1/1/1996· The dominant structures of a coke were determined by observing the microstructure using a point method on 8-12 particles per coke type or lot. The individual particles had a length in excess of 15mm and a thickness of at least 10 mm. Typically 250 counts per particle were made to ensure an accurate evaluation.

The lam coke can replace coke (met coke) and widely used in chemical industry, smelting, gas industry. The semi coke is using the fine quality fired Jurassic coal from Shenfu coalfield, as a new type of carbon materials, semi-coke with its high fixed carbon, high resistivity, high chemical activity, low ash, low sulphur and low phosphorus, is widely used among the Chinese smelting factories.
The best material is synthetic graphite, then petroleum and pitch coke, and the least favourable material is anthracite. Yet the problem is that materials from all of these groups are similar in their chemical analysis, with carbon content variation only in the range of 1%–2% (98%–99.7% C for the synthetic graphite grades, 97%–99% for petroleum coke and 93%–95% C for anthracite) [ 6
