The main aim of the present study was to investigate the characteristics of products from hydrothermal treatments of cellulose in an autoclave at various temperatures (200 °C–400 °C) and residence times (5 min–2 h). The gas products mainly consisted of CO2, CO, CH4, and H2 at...

Hydrothermal carbonization of water hyacinth was experimentally conducted in the range of 30 min to 24 h at 240 °C, chemical and structural properties of hydrochar products were investigated. Oxygen/carbon ratio, and hydrogen/carbon ratio in all hydrochar products were 0.19–0.45, and 0.94...

Based on the geological data of the Qinghai-Tibet plateau permafrost, such as the permafrost ground temperature, the thermal gradient within and below the frozen layer, we numerically investigate the gas production potential from hydrates at the DK-3 drilling site of the Qilian Mountain...

The combination forms of the hydrate dissociation methods in different well systems are divided into 6 main patterns. Dissociation processes of methane hydrate in porous media using the inverted five-spot water flooding method (Pattern 4) are investigated by the experimental observation and...
