A study was carried out in both inert and CO 2 atmosphere to investigate the interaction mechanism of K 2 CO 3 with graphite and coal char during the catalytic gasification of coal char. The formation of K 2 CO 3 catalytic precursors was identified by using series of different techniques. The results obtained in an inert atmosphere show that the interaction between K 2 CO 3 and carbon readily ...

Due to the serious impact of accelerating global climate change, the United States and China signed the China Joint Announcement on Climate Change in 2014, which imposed significant restrictions on the coal industry.
Most of the coal produced in the PRB supports electric power generation in the United States. Starting in the 1990s, many coalfired power plants switched to subbituminous coal from the PRB—which has relatively low sulfur content—to meet tightening Clean Air Act emission 2003, the Powder River Basin yielded more coal than the Appalachian coal basins in the eastern United States.

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 ...
