Basic Research on Reducing Emission of CH₄ Based on Gas Hydrate Technology

Abstract:

Methane (CH4) a potent greenhouse gas (GHG). Human activities, such as natural gas extraction, natural gas transportation and coal mining, result in emissions of the large amounts of CH4 into the atmosphere. Thus it is necessary to study the reduction of CH4 in these fields. The experiments of hydrates formation of CH4 and coal mine gas were respectively carried out using self-developed experiment apparatuses. The results show that the hydrates of CH4 and coal mine gas are prone to be formed under appropriate conditions. The strong storage stability of natural gas hydrates was approved by the experiments to determine the dissociation heat and the average dissociation rate of hydrates. At the same time, the technology flow for recovery and utilization of coal mine gas was proposed based on gas hydrate technology. The experiment results and the former literatures indicate that the reducing emission of CH4 using gas hydrates is feasible.
