A new mathematical model is proposed for the estimation of CO2 gasification kinetics of different rank coals and ash contents. There are no previous reports on the determination of the conversion rate or even residence time of CO2 or steam gasification based on coal characterization and for a...

A comparative study on CO2 gasification kinetics of flax straw char produced by two different processes, namely, torrefaction and pyrolysis was investigated using a TGA (thermogravimetric analyzer). The objective of this research was to investigate the diffusion and surface reactions that occur...
