optimum petroleum coke and pitch


The results show that the average pitch film thickness for the mix containing butts as coarse filler is lower than the mix containing petroleum coke as the coarse filler. These data suggest that pitch penetrates the accessible porosity of butts particles more readily, thus resulting in a thinner layer of pitch around the external surface.
