Abstract Proposed technological classification of low-rank coal has two stages. First part, presented in graphic form, sets the rank of coal, grade of coal and its petrographic character. In order to assess the rank and distinguish various subcategories of low-rank coal, random reflectance of ulminite B/collotelinite has been applied.

In the ISO11760:2022 standard, the classification of coal rank is given, namely, mum vitrinite reflectance less than % is always classi-fied as low-rank coal in China. 28 Following ISO17246:2022 standard, the proximate analysis of coal samples with sizes of mm was conducted on an automatic proximate analyzer. The Langmuir volume V L) and Langmuir …
