Determining Crystallite Size in Calcined Petroleum Coke

In the methods described in the ASTM D5187 standard, a simplified version of the Scherrer equation is used. While all three methods give similar results (MAUD: 48.1 Å; JADE: 42.0 Å; ASTM D5187: 18.5 Å), the differences are generally due to slightly different algorithm used by the programs and the susceptibility to errors of the FWHM determined according to the ASTM D5187 standard.

Volatile matter (VM) analysis of green petroleum coke is an important measurement for determining the calcination behavior and properties of calcined coke. Green cokes with high VM (>12%) are more difficult to calcine and result in a higher porosity and lower bulk density in calcined coke.
