VIBRATED BULK DENSITY (VBD) OF CALCINED PETROLEUM COKE AND IMPLICATIONS OF CHANGES IN THErnASTM METHOD D4292

摘要

Vibrated bulk density (VBD) is a quantitative measurement usedrnin the aluminum industry to evaluate the density of calcinedrnpetroleum coke. In the calcining industry, the reproducibility ofrnthe current ASTM International (ASTM) method D4292 generatesrna wide range of VBD data. Therefore, Oxbow Calciningrninvestigated the VBD procedure – D4292. Issues with D4292rninclude the use of the appropriate crushing equipment, crushing ofrnthe gross sample, sieving of the prepared sample, determination ofrnthe sample volume using appropriate graduated cylinder vibrationrntime and apparatus setup. This investigation led to a revision inrnthe ASTM D4292 method.
