✦ Synopsis

The mobility of alkali and alkaline earth elements loaded on carbon black during heat treatment up to 1123 K in an inert atmosphere was investigated by different spectroscopic methods. The objective was to improve our understanding of gasification by catalysts containing these elements. It was found that Na, Rb, Cs, Sr and Li species migrated into the bulk of carbon on heating up to 1123 K in a flowing inert atmosphere.
