Vibrated bulk density, VBD, is an indicator of calcined petroleum coke porosity, which affects its suitability for use in pitch-bonded carbon applications. (Warning8212;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. Particle size range tested should be agreed upon by the purchaser and supplier.) Note 18212;An example of the use of VBD to characterize coke for prebaked anodes for aluminum smelting is reported by Belitskus who found particles passing through a 0.59-mm opening, No. 30, sieve and retained on a 0.30-mm opening, No. 50, sieve to be preferred. Other popular ranges are particles passing through a 2.36-mm opening, No. 8, sieve and retained on a 1.17-mm opening, No. 16, sieve for the continuous Soderberg anode process and particles passing through a 6.68-mm opening sieve (equivalent to a 3-mesh Tyler Standard Series) and retained on a 3.33-mm opening, No. 6, sieve for graphite electrode manufacture.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. 1.2 The procedure is limited to particles passing through a 6.68-mm opening sieve (equivalent to a 3-mesh Tyler Standard Series) and retained on a 0.21-mm opening sieve (equivalent to a 65-mesh Tyler Standard Series). Further, the procedure is limited to a specific test sample having particles retained between screens having openings that differ by a factor of less than 2 and preferably less than 2. 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.

The test is designed to quantify the amount of dust control material added to calcined coke. The dust control material is applied to calcined coke to help maintain a dust-free environment. It generally serves no other useful purpose. It adds weight to the coke and can have a negative effect on the quality of carbon and graphite artifacts made from the treated coke. For these reasons the coke customer wants to know the amount of dust control material on the coke and can specify a maximum level.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 (dichloro-methane).Note 18212;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 standard.
