Description
In order to investigate the gasification mechanism, structure characterization of char is one of useful approaches. Solid state NMR measurements were performed for raw coals and chars obtained by a drop tube furnace (DTF) at 800, 1200, and 150℃. Demineralized chars treated by hydrochloric acid were also evaluated. Both of the chemical shift and the FWHM obtained by NMR spectra show good relationships with the size of carbon hexagonal network plane. Some structural differences were observed after demineralization because of a damage by strong acid.
