Transformation of char structure and alkali and alkali earth metallic species during pyrolysis and gasification
MetadataShow full item record
This study focused on the formation and transformation of nascent char structure during the pyrolysis in He and the gasification in CO2/O2 of biomass and low-rank coal. The effects of nascent char structure and the concentration of AAEM species on nascent char reactivity were investigated. The results will be useful for the development of low-emission gasification-based technologies for the utilisation of biomass and low-rank coal.
