This research focused on the feasibility and stability of applying the forward and reverse combustion approach to the in situ gasification of lignite and bituminous coal with oxygen or oxygen–steam mixtures as gasification agents, especially reverse combustion gasification. A high-quality...

A high-pressure fixed bed reactor was used to study the formation condition of K2CO3·1.5H2O and the significance of K2CO3·1.5H2O in reducing the regeneration energy required for potassium-based sorbents. The reaction heat of K2CO3 converted into KHCO3 in the following reaction:...
