Visual evidences to understand the interactions between hydrate decomposition and heat/mass transfer are currently lacking. This study proceeds from the hydrate morphology to visualize the interactions between depressurization-induced hydrate decomposition and heat/mass transfer from different scales. Reactor-scale hydrate distribution evolution sh...

Memory effect of gas hydrate is a double-edged sword in hydrate-based application and natural gas hydrates exploitation. In this work, in order to acquire a comprehensive understanding of memory effect, we conduct a series of experiments on hydrate reformation and dissociation under different grain filling patterns and thermal history conditions. E...
Chemical looping gasification (CLG) of Yunnan lignite with Fe-Mn mixed oxygen carriers (OCs) was performed to achieve high purity synthesis gas and reduce pollutant emissions. The Fe-Mn composite OCs presented the characteristics of oxygen decoupling, and there is a synergistic effect between the active components using various analytical methods. ...
A coal chemical looping combustion (CLC) power plant (600 MW) with CO2 capture was established and validated. The key operation parameters and conditions for the coal chemical looping combustion process were tested and optimized. Heat exchange network (HEN) was established and optimized using the combined pinch and exergy analysis method for matchi...
The intermittent depressurization may sustain hydrate production. But its production features and influencing factors in the real setting have not been clear. Thus, the intermittent depressurization with the participation of the water layers was performed in the laboratory samples. The hydrate production features were studied from pressure changes,...

Gas hydrate found in nature is mainly existed in deposit, such as marine deposit and permafrost. The thermophysical properties of the deposit are largely influenced by the formation features of gas hydrate, thereby affecting the hydrate production. In this manuscript, the experiments of formation and decomposition behavior of gas hydrate in the dep...
