Significant Mid Volatile Coking Coal Structure Discovered

Aug 13, 2015 · These clean samples along with AN15-007c (5.85% ash db) were sent to Pearson Petrography for analysis. The objective was to confirm coal rank through reflectance (Ro Max) measurements. It should be noted that the oxidized nature of these samples makes it difficult to measure reflectance from unaltered Vitrinite grains.

The quality of Western Canadian coking coal CIM Store

The quality of Western Canadian coking coal show them to be rich in the inertinite macerals, macrinite, fusinite and semifusinite. When the mean maximum reflectance of vitrinite in oil (R0 max) is used as the coal rank parameter, this high inertinite content is reflected in the lower volatile-matter yields, but the relatively inert
