    Relative to the rotary kiln results in Table 1, the shaft CPC with a TDS level of 50% has a much higher RD. This is despite a similar level of micro-porosity as measured by Hg porosimetry. This means that the decrease in RD from TDS in a rotary kiln cannot be due to the increase in micro-porosity. Table 1 Results from rotary kiln TDS trial

    Calcined Petroleum Coke (CPC) is manufactured from Raw Petroleum Coke (RPC) by the process known as high temperature pyrolysis. The process is carried out in a rotary or vertical kiln at temperatures exceeding 1300 deg C. Calcination of CPC is essentially a high temperature treatment in which the carbon to hydrogen ratio of RPC is increased from 20 to 1000 and above

    Influence of Coke Calcining Level on Anode Real Density

    (CPC) during production, real density (RD) and crystallite size (L C) are key measures for coke calciners [1]. For rotary kiln calcined coke, calcination levels typically range from an RD of 2.04 to 2.07 g/cm3 and L C of 24 to 29 . Due to the different technology of a shaft calciner, the residence times

    Calcinations of coke are usually done in a rotary kiln at about 1300 C to 1500 C. During the process the coke is further decomposed, increasing in the carbon to hydrogen ratio from 20 of green coke to 1000 for calcined coke. Along with increasing in the fixed carbon of the coke to over 95%, electrical conductivity
