Abstract

This work introduces tow solid-state 13C Nuclear Magnetic Resonance(NMR) methods, cross polarization- total suppression of sidebands/magic angle spinning (CP-TOSS/MAS) and direct polarization/magic angle spinning (DP/MAS), for detecting chemical structure of coal combustion emissions. The CP-TOSS/MAS NMR experiment result of the standard sample overestimate the value of sp3-C group (25±5%). This is also demonstrated in the Pingdingshan coal combustion emissions sample. DP/MAS NMR is more accurate in detecting the structure of compounds, but this method need much more time.
