... in this study. In the experiment, fine ice particles, the diameter of which was about 0.5 μm, generated by an ultrasonic mist generator, was confined in a reaction cell with pure CO2 gas under the condition of 0.7 MPa and 253 K to form CO2 hydrate. The conversion rate of ice to hydrate was obtained as a time...
