文摘

A reactor with optical ports and TGA suited for single particle gasification was developed. Inhomogeneous particles affect gasification kinetics. The surface temperature of single particles was measured during gasification. A relationship between particle surface temperature and reactivity was discovered. Quantitative gas analysis with in-situ Raman spectroscopy was performed.
