The objective of this work was to study the catalytic gasification of a subbituminous coal from the Powder River Basin (PRB) using a CO2 and H 2O mixture as the gasifying agent. Sodium and iron, in the form of inexpensive compounds, were chosen to catalyze the coal gasification.
Competition between H2O and CO2 during the gasification of Powder River Basin coal article{Wang2017CompetitionBH, title={Competition between H2O and CO2 during the gasification of Powder River Basin coal}, author={Ying Wang and David A. Bell}, journal={Fuel}, year={2017}, volume={187}, pages={94102} }
The mechanisms of char gasification in the mixture of H2O and CO2 are not clear, and some problems are yet to be solved. The LangmuirHinshelwood (LH) model of char gasification in the mixture of H2O and CO2 and the inhibition effect between charH2O and charCO2 reactions are two controversial issues among these problems. This paper presented new data to elucidate these two issues ...
