Influence of Coke Calcining Level on Anode Real Density

Pilot anode testing Anode baking Coke L C Anode L C Introduction To control the calcination level of calcined petroleum coke (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
