It is one of useful approaches to utilize a char which is a reaction intermediate of gasification as a probe to elucidate the gasification mechanism. It has been generally believed that the solid state NMR measurement for a char is impossible and the investigation has been scarcely reported. In this work, however, it is demonstrated that the measurement is possible at least for the char made up at temperature to 1500℃. It is effective for some chars to dilute them by pottsium bromide or to measure at low temperature. Structural characterization of char is possible by FWHM and peak position of chemical shift.
