文摘

As a preliminary step to the development of a CO₂ capture process under high pressure conditions, an experimental kinetic study of CO₂ hydrate formation has been carried out in a high-pressure batch reactor, using as water-soluble additives a mixture of tetrahydrofuran (THF) and surfactant (sodium dodecyl sulfate, SDS). Used together and in suitable concentrations, these two additives were found to be very efficient for promoting CO₂ capture.
