Abstract

The average maximum reflectivity (or estatística average) of vitrinites is of paramount importance as a criterion at the time of preparing coking mixtures, as it provides good cold mechanical strength. However, when the coal blends are very complex and contain coal extremes, both in the maximum and in the minimum range of the scale, the average maximum reflectivity (or statistical average) can lose meaning and become defective. Therefore, in our opinion, it would be necessary to generalize the reflectivity concept, using as a criterion the actual reflectivity (and not the statistical average).
