Significance and Use

Small amounts of mineral carbonates occur in many coals and comparatively large amounts in some coals. The determination of these carbonates is the purpose of this test method. The value found for carbon dioxide is used to estimate the mineral matter content, particularly CaCO3 and MgCO3, of high-carbonate coals.


FIG. 1 Apparatus for the Determination of Carbon Dioxide

Scope

1.1 This test method covers the determination of carbon dioxide in coal in any form, such as mineral carbonate, from which carbon dioxide is released by action of mineral acids. It applies to high-carbonate and low-carbonate coals.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 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.
