However, the crushing strength of the product employing pitch coke is 1 1/2 times that of the one employing petroleum coke. The carbon product produced from the metallurgical coke is found to be slightly inferior in respect of density and electrical resistivity and slightly superior in respect of crushing strength when compared with that made from petroleum coke.
The electrodes have crushing strength of 350 kg/cm 2 and apparent density of 1.5 gm/cc when impregnated with catalyst and formed into single cell, had open circuit voltage of 1.205 V (0.85 V current density 29 milliamp/cm 2 in 5 M KOH, ideal being 110 milli-amp/cm 2 at 0.8 V).
simple crush strength test was developed to test the pellet strength after drying and calcining and this was useful to check the performance of different binders and pelletizing conditions. The crush strength typically increases by a factor of 3-4 times after calcining due to pellet densification. Figure 1. GPC fines, ACP and Calcined ACP 4.

Consequently, calcined coke preparation crushing steps can dramatically affect the VBD result. Data, showing how calcined coke particle size and crushing steps affect the VBD result will be presented. These data help explain why the roll crushing steps need to be controlled to improve VBD repeatability and reproducibility.
