2020/4/18· Petroleum coke is the product of carbonization of petroleum refining residue after high temperature treatment. It is characterized by low ash impurity content, high temperature liquid phase arrangement and easy graphitization. It is one of the by-products of petroleum
Calcium Petroleum Coke This calcined petroleum coke S content only is 0.1%, fixed carbon(F.C) can be 98% min. Graphitized Petroleum coke 1.Characteristics: High carbon, low sulfur, low nitrogen,high graphitization degree,high carbon recovery (92% ~ 98%
Petroleum coke is a coustible solid product obtained from petroleum residue petroleum pitch after coking. It is dark and porous, and the main element is carbon. Ash content is very low, and less than 0.5%. Petroleum coke is easily graphitized carbon, it is widely
Petroleum coke can be divided into delayed coke and fluid coke according to their coking processes. These two kinds of petroleum coke, although with similar elemental compositions, normally have significant differences in their physicochemical structures. In this study, the carbon microcrystal structures of these two petroleum cokes were first characterized using X-ray diffraction and Raman
The experimental results show that compressive strength and volume density of graphite blocks containing 30% of petroleum coke are 1.366 g/cm3 and 4.8 MPa, respectively, resistivity drop from 114µΩm to 13µΩm, mostly in accordance with block production
For petroleum coke which is poor with pore structure, the obvious graphitization is that the gasifiion rate decreases rapidly in the later stage of petroleum coke gasifiion. So typical kinetic models without consideration of the microcrystal structure cannot give good performance in describing the variation of gasifiion rate with conversion for petroleum coke.
The addition of coal to petroleum feed, i.e., vacuum resid or decant oil, reduces the concentration of large isochromatic units in a co-coke structure, thus leading to a graphitic structure that lacks anisotropic character upon graphitization of the co-coke.
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.
