DENSITY, RELATIVE DENSITY, AND SPECIFIC GRAVITY VIBRATED BULK DENSITY OF CALCINED PETROLEUM COKE: ASTM D4292
Vibrated bulk density (VBD) indicates the porosity of calcined petroleum coke, which affects its suitability for use in pitch-bonded carbon applications. This property is strongly dependent upon average particle size and range. VBD tends to increase with decreasing coke size. The procedure is limited to particles passing through a 6.68-mm opening sieve and retained on a 0.21-mm opening sieve.
TEST SUMMARY
After appropriate crushing the calcined coke with a jaw crusher and roll crusher, 100 g is measured after vibration and the bulk density is calculated.
TEST PRECISION
This test method has a repeatability of 0.014 and a reproducibility of 0.046 g/cm3.
This test method is empirical and no statement as to bias can be made.
