• 9. Evaluation of Average Structure of Anthracites by TPO, TEM and XRD Analyses

抄録

In the previous study, the evolution of H_2O, CO and CO_2 during temperature-programmed oxidation (TPO) of three Chinese anthracites was analyzed. The sources of evolved H_2O are not only organic moiety, but also from adsorbed water and mineral matter. By eliminating the latter contribution, we determined the amounts of H and C evolved only from organic moiety of anthracite. These data then gave us useful information on the structure of anthracite. In this study, an average structure image was drawn based on the TPO data, and an average layer size was calculated. Furthermore, the average layer size of anthracite was evaluated from TEM image analysis. In addition, the crystallite size, L_a, of stacked graphene layer of anthracite was evaluated by a conventional XRD analysis method. The order of these size corresponded well to each other.
