Basic characteristics of coking coal submaceral based on weighted calculation
Abstract：In order to investigate the influence of coal lithotypes on coal utilization,the submaceral was selected as investigation factor,its basic characteristics were investigated.Based on submaceral's weighting characteristic of true relative density,volatile matter and elementary composition,the basic characteristics of typical coking coal were analyzed by experimental analysis and mathematical calculation.The results showed that under the same metamorphic grade F and Ma had larger true relative density,then SV,C1 and C2 had relative smaller true relative density.Volatile matter of different submacerals from big to small was C1,C2,SV,F,Ma.Carbon element content and aromatic-carbon ratio from small to big was C1,C2,SV,F,Ma.Hydrogen content,oxygen content,H/C and O/C were different from carbon element content.
