D02.05.0D - Petroleum Coke

SIGNIFICANCE AND USE
Vibrated bulk density (VBD) is an indicator of calcined petroleum coke porosity, which affects its suitability for use in pitch-bonded carbon applications. (Warning—Vibrated bulk density for a sample of calcined petroleum coke is strongly dependent upon average particle size and particle size range. Bulk density tends to increase with decreasing coke size. A narrow particle size range for this test minimizes the possibility for variation due to skewing of the test sample toward either screen defining the sample.)
SCOPE
1.1 This test method covers the determination of bulk density of a representative 2-kg sample of calcined petroleum coke, after vibration to increase compaction, using a semi-automatic apparatus.
1.2 The procedure is applied, but not limited, to particles passing through a 4.75-mm opening sieve and retained on a 1.18-mm opening sieve. Further, the procedure is applied, but not limited, to a specific test sample having particles passing through a 0.85-mm opening sieve and retained on a 0.425-mm opening sieve. This procedure could also be applied to other sieve fractions being agreed on in the aluminum industry as specified in Annex A1.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

SCOPE
1.1 This test method covers the determination of the amount of material applied to calcined coke to control dust associated with coke handling and transportation.
1.2 This test method is limited to those materials that are soluble in a solvent that can be used in a Soxhlet extraction type of apparatus such as methylene chloride (dichloromethane). Note 1-Methylene chloride is the most popular solvent for removing dust control oil at the time this procedure is being written. Toluene and methyl chloroform, however, have been used with equal results on all cokes tested which have included only those sprayed with aromatic or waxy materials.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8.

SCOPE
1.1 This test method determines the volatile matter produced by pyrolysis or evolved when petroleum coke, or both, is subjected to the specific conditions of the test. Samples having a thermal history above 600°C are excluded.  
1.2 This test method is empirical and requires the entire test procedure to be closely followed to ensure results from different laboratories to be comparable.  
1.3 This test method is not satisfactory for dedusting material content.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8.
