Properties and application of additive enhanced CO2 hydrates

CO2 hydrates are a promising but yet unused material basis for the development of key technologies in the field of technical applications in separation and energy technology. The application potential of CO2 hydrates to desalinate sea water, to treat crude oil and separate light fractions or to recover enzyme from reversed micelle solutions could be shown in principle, but yet isnt scientifically-technically developed further on. The ability to control the process of CO2 hydrate formation or dissociation by various additives is crucial. Such additives may affect both kinetics and thermodynamics of hydrate formation and dissociation. One of the objectives of this study is to establish appropriate methods to characterize processes, so that additive effects on structure and properties of CO2 hydrates could be investigated.
