The equipment is mainly used for high temperature heat treatment of carbon materials, radiation resistant materials, carbon nanometers, carbon fibers, negative materials, graphite powder, rare earth, petroleum coke, coke, Rh materials, contact terminal ma
Utilization of petroleum coke in the rejuvenating Nigerian metallurgical industry is currently satisfied by importation from more industrialized nations of the world such as the USA, Brazil and Venezuela where delayed coking plants operate and grow in nuer. The
China Low Sulfur Pet Coke/Calcined Petroleum Coke Price Per Ton, Find details about China Calcined Petroleum Coke, 6.High graphite crystal nucleus and high graphitization degree: it can reduce the iron liquid contraction tendency and improve the 7.It
for all of the materials. Although a relatively high density was achieved with petroleum coke, flexural tests revealed this material to have very limited strengths. X-ray analysis revealed a high degree of graphitization for the petroleum coke billet but only a limited
The petroleum coke is a by-product of refining crude oil, the impurity content in petroleum coke is high, it can not be directly used as a carburetant , it must be calcined at first . The graphitization can reduce the content of impurities in the carburetant, increase carbon content and reduce sulfur content.
The main materials of graphite electrodes factory factory manufacturing are petroleum coke, asphalt coke, coal asphalt and other materials. Graphite electrode is a kind of graphite conductive material with high temperature resistance. It is a high- quality material made by calcining, mixing, kneading, molding, calcining, impregnating, graphitization and mechanical processing.
The study of graphitization mechanism for petroleum coke, needle coke, and some model compounds (e.g., acenaphthylene, fluorene, and anthracene) is now well developed [32 – 34].
24/7/2020· Non-graphitising carbon materials typically cannot be converted to graphite without the use of metal alysts. Here, alyst-free, high-temperature pulsing is shown to convert polyvinylidene

Currently, there exist concerns over a short supply of traditional precursor coke, primarily due to a steadily increasing price of petroleum. The main goal of this study was to study the anisotropic and isotropic properties of graphitized co-cokes and anthracites as a way of investigating the possibility of synthesizing isotropic or near-isotropic graphite from co-cokes and anthracites.
"graphitization under pressure" ： "graphitization region" ： ( electrically calcined anthracite ) rationed petroleum coke and pitch coke and quantitative pitch used as raw materials by the conventional carbon technics
The coke is further purified by heating to about 1200C to remove residual hydrogen and to develop the crystal structure. The product is then ground to particle size dependent on the end use and for a fine graphite, a flour with a particle size<8.4μm is produced and is subsequently mixed with a carefully selected grade of coal tar pitch, which has a low softening point and high carbon content
