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 novel procedure to perform carbon dioxide (CO2) gasification studies was tested with two different Alberta coals and compared to the most common procedures using thermogravimetric analysis (TGA). The designed experiments indicate that maximum reaction rates reported in the literature were...
