To investigate the gas production from methane hydrate-bearing sediments, the gas production processes from methane hydrate in porous media using depressurization, two-cycle warm-water injection and a combination of the two methods were characterized in this study. The methane hydrates were...

Gas hydrates are considered as a potential strategic energy source for sustainable development. The thermal properties of hydrate-bearing sediments govern the hydrate dissociation behavior and gas production process that accompany phase transformation and multiphase flow. This paper presents a...

In November 2008, gas hydrate samples were recovered during the scientific gas hydrate drilling project conducted in the Qilian Mountain permafrost located in the Qinghai-Tibet Plateau, China. This region is expected to become a strategic gas hydrate exploitation area in China. Based on the gas...

The purpose of this study was to obtain the characteristics of CO2 hydrate formation and dissociation by using different experimental modes and pressures with glass beads. From the experiments, it was found that hydrate forms rapidly in each cycle, especially at high pressure. Hydrate blockage...

CO₂ hydrate formation and dissociation is crucial for hydrate-based CO₂capture and storage. Experimental and calculated phase equilibrium conditions of carbon dioxide (CO₂) hydrate in porous medium were investigated in this study. Glass beads were used to form the porous medium. The...

The heat transfer analysis of hydrate-bearing sediment involved phase changes is one of the key requirements of gas hydrate exploitation techniques. In this paper, experiments were conducted to examine the heat transfer performance during hydrate formation and dissociation by a thermal method...

Hydrate-based CO2 capture is a promising technology. To obtain fundamental data for a flowing system, we measured the distribution of pore solution to analyse hydrate formation/dissociation and gas separation properties. An orthogonal experiment was carried out to investigate the effects of...

The continuous high-purity hydrogen production by the enhanced-sorption chemical looping steam reforming of glycerol based on redox reactions integrated with in situ CO2 removal has been experimentally studied. The process was carried out by a flow of catalyst and sorbent mixture using two...

Over the past century, fossil fuels have provided the majority of China's energy. However, their extensive utilization leads to a shortage and environmental pollution. Recently, submarine and permafrost gas hydrate deposits have been investigated as a possible clean and sustainable energy source...

Several studies have demonstrated that methane production from hydrate-bearing porous media by means of depressurization-induced dissociation can be a promising technique. In this study, a 2D axisymmetric model for simulating the gas production from hydrates by depressurization is developed to...
