(Test Method)Standard Test Method for Volatile Matter in Green Petroleum Coke Quartz Crucible Procedure
Standard Test Method for Volatile Matter in Green Petroleum Coke Quartz Crucible Procedure
SIGNIFICANCE AND USE
The volatile matter of petroleum coke affects the density of coke particles and can affect artifacts produced from further processing of the coke.
The volatile matter can be used in estimating the calorific value of coke.
SCOPE
1.1 This test method covers the determination of the volatile matter produced by pyrolysis or evolved when petroleum coke is subjected to the specific conditions of the test method.
1.2 The interlaboratory study for precision covered materials with a volatile matter concentration ranging from about 8 to 16 %.
1.3 Samples having a thermal history above 600°C are excluded.
1.4 This test method is empirical and requires the entire test procedure to be closely followed to ensure that results from different laboratories will be comparable.
1.5 This test method is not satisfactory for determining de-dusting material content.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 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 to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
