441 Fundamental examination on the dissociation and expansion characteristics of CO_2 hydrate using the gas-hydrate generator

Abstract

Focused on the differential pressure at the time of generation of gas hydrate dissociation, do the operation of the engine generator of high pressure gas. Generates the CO_2 hydrate by using a fluid mixture of water and CO_2. Further, dissociate from heating CO_2 hydrate. Investigated the cycle of CO_2 hydrate dissociation and generation. Is that filling the CO_2 gas 3MPa in the water 50ml as an initial condition, repeating the cooling and heating -5t and 30 °C it, can be obtained continuously a pressure differential of about 0.7MPa.
