In this communication,the impacts of adding SDS (sodium dodecyl sulfate),TBAF (tetra-n-butylammonium fluoride) and the mixture of SDS + TBAF on the main kinetic parameters of CO2 hydrate formation (induction time,the quantity and rate of gas uptake,and storage capacity) were investigated.The tests were performed under stirring conditions at T =5 ℃ and P =3.8 MPa in a 169 cm3 batch reactor.The results show that adding SDS with a concentration of 400 ppm,TBAF with a concentration of 1-5 wt%,and the mixture of SDS + TBAF,would increase the storage capacity of CO2 hydrate and the quantity of gas uptake,and decrease the induction time of hydrate formation process.The addition of 5 wt% of TBAF and 400 ppm of SDS would increase the CO2 hydrate storage capacity by 86.1% and 81.6%,respectively,compared to pure water.Investigation of the impact of SDS,TBAF and their mixture on the rate of gas uptake indicates that the mixture of SDS + TBAF does not have a significant effect on the rate of gas uptake during hydrate formation process.
