Abstract This study analyzed the partial effect of carbon dioxide hydrate in reaction kettle experiments. The particle and
bubble characteristics of the crystal nucleus during carbon dioxide hydrate decomposition were observed under
the microscope. The results showed that in the temperature range of 0.5°C–3.5°C, the pressure range of 3 MPa–
5.5 MPa, phase characteristics in the reaction kettle changed in a complex fashion during carbon dioxide hydrate
formation. During hydrate decomposition, numerous carbon dioxide bubbles were produced, mainly by precipitation at high temperatures or in the hydrate cage structure. The hydrate crystal nucleus initially exhibited fluidity in
the reaction. However, as… More >
