CO2 gasification of Powder River Basin coal catalyzed by a cost-effective and environmentally friendly iron catalyst

Zhang, Fan; Xu, Deping; Wang, Yonggang; Argyle, Morris D.; … - In: Applied Energy 145 (2015) C, pp. 295-305

CO2 gasification of a sub-bituminous Wyodak coal from the Powder River Basin (PRB) was conducted in a fixed-bed laboratory gasifier at atmospheric pressure with FeCO3 as a catalyst precursor. The effect of iron on the coal pyrolysis was evaluated by thermo-gravimetric analysis (TGA). Scanning...
