英文摘要The separation of carbon dioxide (CO2) by hydrate-based technology has attracted much attention due to its low energy consumption and simple process. In view of the problems of slow hydrate formation and low gas consumption the factors influencing the hydrate-based separation of CO2 from integrated gasification conbined cycle (IGCC) syngas in the presence of cyclopentane (CP) are systematically studied in this paper. The results show that CP helps to promote the formation of CP-CO2 binary hydrate, and the gas consumption is affected by hydrate formation mode and hydrate density. The denser the hydrate phase is, the lower the gas consumption is. At the optimum condition of 275.65 K and 4.45 MPa with CP of 5v%, the highest gas consumption of 0.0128 mol/mol is obtained. The gas-hydrate contact is an important factor affecting gas consumption. In the hydrate formation system, the liquid often exists between gas and hydrate, limiting the full contact of gas and hydrate. Therefore, in the process of hydrate formation, making the hydrate fully contact with the gas without being covered by the liquid is a way to improve the gas consumption. (C) 2020 Elsevier Ltd.
