Abstract

This paper studies the hydrate formation kinetics at 273.2 K and an initial pressure of about 5 MPa in powder hydrogel systems stabilized by hydrophobic nanoparticles. The influence of composition of the aqueous phase used to saturate the hydrogel on hydrate formation kinetics was investigated. The stability of the systems in hydrate formation - dissociation cycles, i.e., their ability to maintain the hydrate growth rate and water-to-hydrate conversion at a high level in multiple reuses, was also assessed.
