The Relationship between Thermal Characteristics and Microstructure/Composition of Carbon Dioxide Hydrate in the Presence of Cyclopentane

Hydrate-based carbon dioxide (CO2) separation and capture is a new technology for achieving CO2 emission reduction. However, it still not commercially applied the ambiguity of microscopic hydrate formation mechanism. In constant volume experiment formation, there are two or more pressure platforms, indicating that might be different hydrates in succession. order to reveal relationship between process gas consumption composition mechanism cyclopentane-CO2 (CP-CO2) system was investigated using differential scanning calorimeter (DSC) Raman spectroscopy. The results indicated CO2-CP binary formed successively, they coexist final hydrate. CP-CO2 forms preferentially, as crystal seeds, inducing hydrates. processes cause pressure-drops. provide scientific basis increasing stages presence promoter.
