The cornstalk-assisted direct lignite liquefaction was conducted by using a resonance agitation micro-autoclave heated by a salt bath. The effects of reaction temperature (360°C, 390°C, and 420°C) and time (5min, 15min, 30min, and 60min) on the distribution and yields of liquefaction products...

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...
